Diesel-Electric Posted September 22, 2015 Share Posted September 22, 2015 Hi I'm new to the hobby and need to know the impact of very long layouts on the power and speed of a locomotive.I have a fairly long layout which is only going to get longer.Currently my outermost curve is a second radius with a single straight piece used at each end to widen it slightly and the equivalent of seven straights at each side to lengthen it. To create the layout I'm going for both are going to be extended a bit and there will be a third radius curve and a siding on a first radius curve as well as a station and goods yard inside the third radius.How much does a long layout effect the power output of a standard power unit as supplied with a hornby kit?What effect will this have on locomotives both in terms of speed and pulling power?

LCDR Posted September 22, 2015 Share Posted September 22, 2015 You will truely have to have a VERY long layout before voltage drop becomes a problem. I had a layout over 18 foot long (circuit was about 45 feet of actual track length, equivalent to well over 16 standard straights each side) at one time and it didn't interfere with the running of trains one little bit. Seven straights will not be a problem. Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 22, 2015 Share Posted September 22, 2015 Outer curve second radius? Does that mean there is a first radius inside it? You won't be able to run anything bigger than an 0-6-0 on that. You might think about 3rd or 4th for the outer and ditch the first entirely.
