More mental trains! In the 1940's it was very clear that diesel locomotives had some big advantages over steam - it was cleaner, cheaper (if you had oil), easier on the crew, more reliable, easier to produce very high power from, and operationally much more flexible. Absolutely none of these problems were solved by O.V.S. Bulleid's insane "Leader" class of 1949. Apparently, what steam locomotives really needed to compete with diesels was to look like a diesel. And so, three years of development by the old Southern Railway, and for some mad reason by British Rail after nationalisation, BR's Brighton works produced this: Well it certainly looked like a diesel. But underneath it was a surprisingly old-fashioned steam locomotive. Basically, all the new and innovative features of the "Leader" were unnecessary or didn't work, and all the things that needed modernising about steam locomotives were left in place. A good example of this faulty thinking was the position of the fireman. The "Leader" had a cab at each end, meaning that the fireman couldn't be in the cab, because the firebox would be at the other end of the locomotive half the time. There were two ways this problem could be solved: 1 - Using a mechanical coal stoker which had been been successfully employed in more modern steam designs in North America and Africa for a couple of decades. 2 - Install the boiler back-to-front, trapping the fireman in a hellbox between the firebox and the bunker in the middle of the locomotive, causing him to get roasted alive as he worked and have to communicate with the driver via a bell on a string. Guess which they chose? Better still, the fireman only had a door on one side of the locomotive, so in the event of an accident in which the locomotive ended up on its side (and given how top-heavy the "Leader" was that was more than likely), he would be trapped in his fume cabin and get either incinerated or scalded to death depending on whether the steam or the fire got to him first. They did install a corridor down the side of the locomotive to enable the driver to change ends. This required the boiler to be mounted to one side, which not only restricted its size (lack of steam was one of the "Leader's" many problems but, more seriously, made it lean severely to one side (the side within which the fireman was sweating), making the ride terrifying and destroying any track and points the "Leader" happened to pass over. This problem was solved by the kind of no-nonsense engineering that won World War II - they filled the corridor with scrap metal, trapping the fireman more completely in his roasting-hot coffin-to-be, making it impossible for the crew to move around the locomotive (a big point of the design in the first place) and adding loads of weight without increasing its pitiful steam production. So, with the wobble cured (and the rest of the crew given earmuffs to cut out the sound of the fireman's screams of fear and pain), they tried to move the train. This did not go well. You will notice in the picture that the wheels of the "Leader" are very unusual for a steam locomotive, sitting in bogies like a diesel rather than the conventional rigid centrally-mounted wheels of a normal steam locomotive. This aping of diesel design required two sets of cylinders, one on each of the pivoting bogies. This required an insanely complicated system of getting the steam to the wheels in the first place (which leaked steam and lubricating oil all over the place), and a design of cylinder valve that hadn't been put in a locomotive for 40 years (and for very good reasons) to get sufficient power to six wheels in a very restricted space. Having two completely unconnected sets of wheels caused a unique problem whereby they would "centre", with the forces on each bogie balancing out, preventing the wheels from moving at all if they happened to be in a certain configuration. It's not quite each set of wheels moving in opposite directions, but it's a similar principle. The upshot was that every now and again, the "Leader" wouldn't physically move unless it got a shove-start from a more sensible locomotive. Also, on the rare occasions that the "Leader" got some steam up, it was found that the cab at the smokebox end of the loco got as hot as the fireman's sweatbox, so in trials the "Leader" was only run in reverse - completely eliminating the one remaining advantage of the locomotive (and the main reason for its pants-on-head retarded design): its ability to run equally well in either direction without needing a turntable. The tests were "notable for their absence of praise" for the "Leader"'s capabilities. It was quietly scrapped in 1951 and British Rail instead ordered a whole bunch of locos that were diesels inside and out - but some of them were almost as terrible as the "Leader", and I'll get on to those in another post.

So they're a lot warmer than LEDs but nowhere near as warm as an incandescent lamp or vacuum tube that needs to get red-hot to work. I have a Nixie clock I built from old Russian tubes. I just went to feel the tubes, and though they're warmer than room temperature, it's barely noticeable. My infrared temperature gauge says they're about eight degrees warmer than the shelf they're on.

Arsenic Lupin posted:Split-flap displays. Did you ever watch Groundhog Day and wonder what was with that weird clock? Well, before LEDs came down in price, digital clocks rotated cards against a ratchet: each time a minute passed, the card slipped in front of the ratchet and a new card was displayed. Since minutes move in an ascending sequence, this worked just fine. There is one of these in 30th street station in Philadelphia and I love it. It is so very loud. When I was a kid (I'm 22,) I also had one on my night stand. I don't remember the number change being annoying, but I do remember it made a constant mechanical wherring noise.

Crap British Trains of the 1950s British Rail 10100 Inspired by the lunacy of the "Leader", British Rail decided that their diesel designs could easily reach equal levels of bugfuck insanity, and proved it with 10100. Whilst the US designs of the period were amazing art-deco masterpieces, 10100 looked like this: Still, the ugly outside succeeded in only drawing attention away from the sheer madness of what was inside. Why have one engine when you can have five? Yes, 10100 had five separate diesel engines, four for traction and one to power the auxiliaries. For many designs, just having five engines jammed into the chassis would be eccentric enough, but no, the madness was only just beginning - for that, we need to examine 10100's truly deranged transmission. Most large diesels use electric transmission - the engine drives a generator or alternator connected to electric motors in the wheels. A few use hydraulic transmission. 10100 was designed for mechanical transmission - physically connecting the engines to the wheels via clutches, shafts and gearboxes. Hence the need for four traction engines - if you put more than about 500Hp through the clutches of the time they'd disintegrate, so to get 2000Hp you needed four. Each of 10100's engines was connected via a hydraulic clutch to a gearbox. Changing "gear" consisted of switching in more engines, 1 in first gear to 4 in top gear. So yes, you read that right, 10100 produced 1/4 of the power when starting as it did at top speed - despite the fact that you clearly need more power to overcome inertia at low speeds or when climbing hills. So to counteract this, the engines were turbocharged, with the auxiliary engine blowing the engines that were engaged, producing 4 times the turbocharging when running on one engine. The astonishing thing is that this Heath Robinson transmission sort of worked, and once 10100 got up to speed it had serious haulage power, though hills were a problem and failure of any of its five engines would cause the locomotive to stop working completely. In 1958 it caught fire, possibly out of shame, and was scrapped. British Rail Class 16 One of the big advantages of diesel traction is that you can easily put a cab at either end and clearly see the line ahead of you instead of having to peer down the side of a massive, smoke-belching boiler. That means you can reverse the locomotive simply by driving it from the other cab rather than using a turntable. This is especially important in a country like the UK (less so in North America) where journeys are shorts and reversing is frequent. But to keep the cost down, and to enable shunting without having to swap cabs every minute, some smaller diesels were built with only one cab. This provided good visibility in only one direction, which was a compromise but saved weight and cost and made maneuvering in yards faster and less hassle. Or you could place the cab like this, giving an equally bad view of the track in either direction: This magnificent piece of design is the BR class 16. Ten of these monuments to uselessness were built. As it happened, the visibility problems weren't so big of a deal, because they were only a problem if the locomotive was moving, which was not often. By the time they were scrapped (not very much time at all), they had spent more time under repair than actually available for servce. Bad design (particularly inadequate engine ventilation) combined with bad manufacturing tolerances on almost every moving part combined to make them the most unreliable diesel ever to run in Britain, and they had fierce competition for that honour (see below). The only reason they lasted as long as they did was that they were under warranty, and the manufacturers, NBL, had to spend so much time and money repairing them (and various other defective diesels that they built for BR) all the time that they went bankrupt. With no more warranty spares, they were withdrawn and scrapped. British Rail Class 17 What's worse than buying a locomotive that doesn't work properly? Buying a locomotive that serves no useful purpose even when it does work. What's worse than buying a defective locomotive that you don't need? Buying 200 of them, that's what. Thus is the disaster story of the class 17. Designed for the kind of light, pick-up freight work that had been lost to road transort a decade before they were even built, British Rail were so pleased with the design that they ordered 200 of them without bothering with a prototype or a pilot scheme (as with the class 16) - despite the fact that the "Clayton", as they were known, was powered by a very similar engine to that in the class 16. So the class 17 flopped around the rail network for a few years, breaking down a lot and failing to serve any useful purpose. Attempts to assign them to heavier freight trains in pairs failed miserably, the hard work causing them to fail and break down even more than usual. BR tried to flog them off to industrial operators, who, being privately owned, actually wanted locomotives that worked. So they were all withdrawn, and aside from one preserved example, scrapped. Some had been in service for less than five years, 10% of their anticipated lifespan. British Rail Class 31/4 Now the class 31, despite being a noisy, underpowered, overweight and sinfully ugly bucket of rivets was actually very successful. It was fast, easy to maintain, and, (once they'd replaced the original engines with ones that actually worked) very reliable. Well British Rail weren't going to let that kind of poo poo go on for long, so they set about ruining one of their better diesels in ingenious fashion. With the demise of steam on BR in the late 1960's it was increasingly pointless to have passenger carriages heated by steam. Most 1950's diesel designs had boilers for this purpose, which were a maintenance headache and increasingly unnecessary. So both coaches and locos were converted to electric heating, usually by tapping some amps from the loco's main generator to feed batteries in the coaches. To offset the loss of traction power this caused, some designs (like the very successful class 47) allowed the driver to temporarily interrupt the train supply when full power was needed, such as when starting or climbing hills. Not so with the class 31. First up, the genuises who planned the conversion decided that the class 31 needed to be able to generate a massive amount of electrical power, despite being a pathetically underpowered rustbucket to start with. The idea was that Class 31s would be attached to crack expresses before they set off to heat the coaches while the bigger, express locos, hung around the green room snorting coke or whatever it is big express locos do instead of pre-heating their own drat carriages. In the event, this almost never happened. Worse, unlike all the other types, there was no way to turn the ETS system off, so the class 31 lost 500 of its meager 1500Hp permanently, whether it was hauling passenger cars, freight, or just crying in the toilets about the loss of a third of its manhood. The 31/4 was so underpowered that in the 1990s, several unconverted examples were re-built with through ETS wiring (as 31/6), to allow one class 31 to heat the train whilst the other actually pulled it. Embarrassing.

Here's a crap American train, the Camel: That's the B&O No. 199, built in 1860, designed by eccentric engineer Ross Winans. It was built to solve the problem of how to burn poor anthracite coal. Winans's solutions was to build a huge firebox on the thing. It was so big that the engineer's controls were moved to the top of the boiler. It had a number of problems:
Whenever modifications were suggested to him by customers, Mr. Winans would angrily shift the blame to the engine crew, railroad maintenance, or anyone else, even going so far as to have two B&O chief mechanics fired for criticizing his engines. His orders quickly dried up.

Ross Winans was not only known for the Camel locomotive. He also build a cigar-shaped iron steamship in 1858, named Winans after himself. In addition to the new hull design, he put the propeller in the middle, but perpendicular to the length of the ship: The problems with this design include:
Winans tested the ship in Chesapeake Bay, but never on an ocean voyage. When the Civil War broke out, he tried to interest the Union in his ship, giving tours of it at its dock in Baltimore. They weren't interested. Here is a contemporary photograph of the ship at dock:

What...what the? I don't even. So when you have one engine going, you have no more torque per engine than you do when you have all four engines going. Your maximum torque being output from the transmission is the exact same, no matter whether you have one engine coupled to the output or all four coupled to the output. This, right here, is peak British engineering. What the gibbering gently caress.

Obsolete locomotives aren't necessarily bad locomotives. Check out the China Rail SY Class: It's fairly unremarkable looking. It takes elements from the best contemporary Russian and American locomotives, and is designed to burn absolutely terrible coal and keep going with minimal maintenance. What's remarkable about it? Thousands have been built, and the type was in production from the 1950s to 1999. Its larger sibling, the QJ 2-10-2, pulled the last regularly scheduled steam-hauled passenger trains, and ran the length of the newly-constructed Ji-Tong Railway in Inner Mongolia. Several QJs and SYs still exist. There are many ppreserved in China. Private operators in China still operate them- SYs are often found in steel mills and coal and ore mines, while QJs pull power plant coal delivery trains. 3 QJs are in the US, 2 have been heavily Americanized in appearance, and one still remains close to its original Chinese appearance. Also, if you're interested in buying one, Motive Power Industries in New Jersey will gladly sell you one.

Meet the Schienenzeppelin! (Rail Zeppelin) It's the answer to "What if you get a zeppelin builder to make a train?". And in the drive to keep up with the Jones (the Russian's Аэроваго́н) you throw massive amounts of money and resources resulting in it being built within a year. You end up with a train that's made of aluminum, fitted out in Bauhaus and pushed forwards by a wooden propeller. Despite the sheer lunacy of this experiment, such as having a massive propeller whirl around a station, it appears to have had worked as it's lightweight construction (20 tons) and a conjoined BMW VI aircraft engine shoved it down the rails at a still set record (for petrol fueled) of 230km/h The biggest problem was that it was a single purpose vehicle. There was no way to link it up to anything. It also lacked the momentum to move up steep gradients as any change in angle would drop the power from the prop. Also it has no reverse. It served a short life as safety concerns kept it out of action and despite a few retrofits it eventually was scrapped to provide materials for war. Many of the concepts (such as streamlining) ended up being used in other trains - such as the Fliegender Hamburger. The concept of combining aircraft and train design had a resurgence in the jet age with turbojet trains.

Did someone say crap British trains? The British Rail Class 140 "Pacer", functionally obsolete for years. Under disability discrimination legislation passed in 1995, these trains must be out of service by 2019, but it's unlikely that will happen. It's a problem that many trains in the North of England are pretty much life expired but there aren't any replacements. And they use two-car Pacers at 5:30pm to take people out of Leeds to the commuter belt stations.

This was the first commercially successful public electric tramway: If you look closely you notice that there is no pantograph and no third rail. It was simply supplied with those 160V DC current through the tracks themselves. The uninsulated tracks running through the middle of Berlin. After too many incidents of people and horses getting electrocuted, they put up a fence and tried to turn off the current on the crossings if no train was nearby. But there still were various incidents of people and horses getting shocked. The city youth also found a new hobby of throwing wires between the tracks to watch them spark and melt as a nice cheap firework. It operated like this for almost 10 Years. Then the pantograph got invented.
