Hello I like to share the result of Spark Industries' new side project. The company produces modern locos and cars, but wants to salute the old times. So designed a steam engine with enthusiasm and love. She is a 4-6-4 Hudson type loco: There wasn't a particular real loco for modelling, but the main shape based on Canadian Pacific 2816 and Union Pacific 844. She looks best on bigger turning radius, but deals with the standart lego curve and switch. The built width is 7..8 studs. The loco is 54 long, and with the tender it's 83. The Big Ben Bricks' XL wheels fitted mostly for the desired scale. Some curiosity: The steam valve is a built in little pneumatic cylinder. PF cable used for pipeline imitation: The handrails on the boiler's two side made of the very old technic flex system's inner cable. Electric side: 2 PF train motor 1 PF L motor 1 PF IR receiver (v2) 1 PF battery box 1 PF extension cable (50cm) 1 PF polarity switch The tender contains all the PF elements, except the L motor and the extension cable. Two train motors are attached to one output of the IR receiver (of course, one of them with the polarity switch). The L motor is in the loco, connected to the other IR receiver out. That way, it's possibble to start the loco with full voltage, the big wheels slipping, and then turn on the main drivers in the tender. Some more pics: Hope You like it!
Some time ago this thread appeared, talking about a substance called "Bullfrog SNOT": After some initial confusion (is this some sort of new building technique?), I learned it was some sort of substance model railroaders could "paint" onto their wheels to add traction. I was pretty sure that it would just be worse than an actual traction tire, and forum posts reviewing the substance seemed to agree with me. The train wheels Lego makes both feature a groove for traction tires already anyway. However, I had been considering a couple things I wanted to model where the correct wheel size is closer to a Big Ben Bricks medium wheel. I didn't trust myself to cut a groove into the wheels without access to proper machine tools, so I thought I'd try the "painted on" traction tires. One key issue, however: I'm kind of a cheapskate, and didn't want to spend $25 on a tiny container of stuff to find out how well it worked. Furthermore, if it did work, and I posted about it, forum members who aren't from the only country to put men on the moon might have difficulty accessing the substance (although Tenderlok seems to have managed somehow). Time to find a substitute. Whatever I found needed to have the following properties: Increase friction (adds traction). Can be applied in a uniform layer. Transparent, so it doesn't affect the appearance of the wheel it's applied to. What has these properties, and is readily available? Urethane caulk from a hardware store! However, caulk is far too thick to apply evenly in a thin layer. The packaging bears the words "easy soap and water clean up"; I took this to mean that I could thin it by adding a small amount of water: I then used a small brush to apply this onto a clean spinning wheel to get an even coating: I left the wheel spinning for about half an hour for the thinned caulk to dry. Here's what it looked like afterwards: I built a small test vehicle and ran it on a figure-eight for about half an hour (so as to test it going around turns both ways). This was the result: legoman666 is remarkably prescient... Pressing down on the test vehicle suggested that the painted-on tire had a bit less traction than an actual traction tire, but traction seemed to remain reasonable after a half hour of running. I wanted a more thorough test though, so Commander Wolf installed the modified wheels on his QJ and had it pull some long cars for most of a BayLUG meeting. The result: This stress-testing caused the tires to wear off. I'm not sure if that's a property of the substance (did I thin it too much?), or perhaps the underlying surface being too smooth for the caulk to adhere well. More testing is in order...
