Hi all, since I like a lot old tin trains (Marx, Hornby) and in particular the clockwork ones, I always wanted to try to create my own clockwork toy train. The first idea was to use the yellow old clockwork motor from the Basic sets of the 80s. Unfortunately, its wheels were designed to accept tires, so double side border and no capability to go through rail switches. From this forum ("Moc Clockwork Steam Locomotive" from RSB04 user) I understood the possibility to change the standard wheels with train wheels and so I did, adding two rubber bands. I can say it works fine, with all its limitations. I ended up creating a "reloaded" 115 set with parts of the 70s I had around. All cars are very light, and I greased the axles with tamiya Mini4WD grease in order to eliminate noises and to reduce drag. On a circle track, it makes 1 and 3/4 turns. On straight track, it travels more or less 4 meters. It is a toy train, no more no less, but I wanted something more modern.
one day I was playing with an old wind up motor i had. I alwase liked the way these motors spun at a fairly slow pace for a long time, rather than spinning all their power away in the first few seconds after winding like most wind up/pull back motors do. thats when it hit me, sence it has such a long run time, just how far would it go on my layout? well, it worked better than you would think, so i carefully removed the road wheels the motor came with and fitted it with a set of blue/grey era train wheels (easier said than done). i decided id make the loco in the classic 80s style sence the running gear was from that time period. the end result? I tried to make it as small and light as possible, its smaller than it looks in the pic, fits in the palm of your hand. heres it is next to 7722 for size comparison. theres just enough room for a minifig in the cab. his head just barely touches the roof. well it was a fun experiment to say the least, the engine isn't exactly what you would call practical, but it works ok for what it is. its actually pretty suprising what it can do, really under rated motors these.
