Better to do all the track revisions first then see whats left at the end Yeah I’ve got a printout of the plan which I have studiously highlighted to check what connects to what.

AyJay Posted January 24, 2021 Share Posted January 24, 2021 Hi James, don't be discouraged. And don't be tempted to rush ahead, 'regret at leisure' and all that. You could try what I tried.... Lay out a length of track on a board and run trains up and down it whilst propping up one end with books etc. See what impact the gradient has on speed and pulling power. I found for a Hornby tender loco and three carriages, that I could go up to 1 in 30 before the impact was 'significant'. This is a subjective thing, only you can decide where that point is for you. However, this gradient may only be acceptable for short inclines. The longer the incline, the greater the effect, also the longer/heavier the load being pulled. Decide on what gradient you can accept for a sustained straight run and then decrease it by 10%. For a curve, that gradient must be at least halved, so for example, a straight 1:40 becomes < 1:80 on a curve. After doing all this, I decided to abandon thoughts of gradients completely and put all the track on the level. Have fun and don't stop considering other options. All the best, Alan Link to post Share on other sites More sharing options...
jamesinyk Posted January 24, 2021 Author Share Posted January 24, 2021 I’ve ordered a polystyrene gradient set to test out whether I can climb enough over a small distance. Lightly pinned the non-flex parts of the track to the board today to see how it feels. Quite pleased with it. Link to post Share on other sites More sharing options...
