Model Railroading > Running on dc only ( a question about curve speed )Date: 06/08/24 06:18 Running on dc only ( a question about curve speed ) Author: Highhood Assuming that every 2' you have power wires going into your track.
also assume that you do not change ( ever ) the amount of power going into the track. Will / should the speed of the train remain the same all the way around the layout or should / will the train be slower going through the curves ? the curves in question are 24"-30" always 3 axle trucks. tia for your response Jon Fink Schenectady, NY Edited 1 time(s).

The train will not slow down as it gets further from the power source.
Victor Baird Date: 06/08/24 06:50 Re: Running on dc only ( a question about curve speed ) Author: pilotblue I would say that a little slowing through a curve would be expected due to friction from the outside wheel flanges rubbing on the inside of the railhead. This wouldn't be electrically related, just normal dynamics. If the slowdown is significant, check to make sure all wheel sets are in gauge and that the trucks swivel freely.

It's good practice.
Victor Date: 06/09/24 10:54 Re: Running on dc only ( a question about curve speed ) Author: zr190 I built my DC layout feeding every 3tf section or placing jumpers at every joint (other than insulated of course) Certainly not every 2 feet.
I've never had any issues with trains slowing down. zr190 Date: 06/09/24 13:37 Re: Running on dc only ( a question about curve speed ) Author: grahamline We apply a feeder to each separate length of rail and do not rely on rail joiners to carry any current. In cases where there are several short lengths we will solder the joints solid. Joints on curves are often soldered as well to maintain curvature but very rarely would that involve more than three lengths of flex track.
