meathdane Posted July 11, 2022 Share Posted July 11, 2022 Just came upon this from TRS trains, all I have to say is WOW! https://fb.watch/ebc5c4fQ1E/ This guy does incredibly work! Especially fitting the generator unit into such a packed locomotive! 7 3 Quote Link to comment Share on other sites More sharing options...
irishthump Posted July 11, 2022 Share Posted July 11, 2022 Yeah that's a major feat of engineering there! I wonder did he use some of the empty space behind the see-through grill... 1 Quote Link to comment Share on other sites More sharing options...

Westcorkrailway Posted July 12, 2022 Share Posted July 12, 2022 I love the weathering in this loco, as I do the smoke. They compliment each other very well. accodning to the manufacture the speaker and decoder was moved to the rear area behind the grill and the smoke machine was put where the decoder once was (smart idea might I add) 4 1 Quote Link to comment Share on other sites More sharing options...

I'm very impressed! I can't imagine it being cheap, but absolutely worth every penny! 1 Quote Link to comment Share on other sites More sharing options...

I think I’d quite enjoy one novelty model like this. 121 fits it well probobly with that extra space within to work with and the fact the prototype often be quite Smokey in the later days of its lengthy career Quote Link to comment Share on other sites More sharing options...
Georgeconna Posted July 13, 2022 Share Posted July 13, 2022 (edited) What are these smoke machines pray tell, Are they made by the lad installing them , Looks to be fan Assisted too? EDIT: Just seen it TRS Trains synchronised smoke 100 notes too! Edited July 13, 2022 by Georgeconna Quote Link to comment Share on other sites More sharing options...
MauriceJ Posted July 13, 2022 Share Posted July 13, 2022 It’s a water atomiser. The “smoke” is actually cold water vapour.. It won’t set off fire alarms or smoke out a room. Quote Link to comment Share on other sites More sharing options...
murphaph Posted July 13, 2022 Share Posted July 13, 2022 They are pretty cool but in reality once warmed up most diesels don't produce these huge plumes of smoke at high revs. The water vapour generation would need more complex control to be realistic, fading out as the revs increased, back in at medium revs then out again at idle. Only a cold engine would typically belch smoke throughout the rev range. Simply coupling the sound frequency to the generation rate may not work that well. The water also has to land back on the layout so that's something to bear in mind. 2 Quote Link to comment Share on other sites More sharing options...

It's hard enough to keep the track and layout clean without that going on. 2 Quote Link to comment Share on other sites More sharing options...

I've seen similar videos of US EMD diesels doing the same thing. 2 Quote Link to comment Share on other sites More sharing options...

I've seen similar videos of US EMD diesels doing the same thing. I think it behaves exactly as I described. Idle no smoke. Pulling away smoke. Cruising speed no smoke. The last minute of the video shows the same loco producing barely a whiff as she gets up to speed. The other 2 locos in the video don't show any signs of smoke at all. You'd need more complicated control of the smoke unit to achieve that behaviour. You can't simply couple it to either the loco speed or loco sound frequency. A loco at full tilt typically wouldn't produce a stream of visible smoke. Only perhaps when moving off. Too fiddly if you have to manually switch smoke generation on and off I feel. 2 Quote Link to comment Share on other sites More sharing options...
murrayec Posted July 16, 2022 Share Posted July 16, 2022 ESU DCC & Lokprogrammer has built in smoke control for ESU, generic, and Seuthe smoke generators, which handles when one wants the smoke to happen. Eoin 4 Quote Link to comment Share on other sites More sharing options...
