Title: Maximum incline percentage for UK HO \ OO scale.
Post by: centenary on September 13, 2011, 08:41:35 PM
Hello.

I know incline percentage can be set to anything reasonable depending on the longest stretch of track and length of train etc.

When I open anyrail to create a new layout, the Maximum Include Percentage defaults to 3%. Changing this is easy.

Im intending to create layouts based on UK HO \ OO scale. The longest stretch of track on my layout would be approximately 5 meters (or a little longer if I run the incline diagonally corner to corner).

So, if we assume my longest straight is going to be 5 meters, what would be a reasonable maximum incline percentage over this distance and would allow one track at its highest point to run over a lower level track? (Hope I explained that clearly!)

Also, is there a formula to work out what the maximum incline percentage should be for any length of track to be raised to a given height?

TIA

Normally, you should not go over 3% or 4% incline, especially with longer trains or curved track. If you do, trains will stall.
If you only run very short trains or trams, perhaps you can try 5%.

1% incline means that you go one unit up for 100 units forward. For instance: 1% is 1cm up per meter.

I hope this helps!

...And, you can get AnyRail to do all the work by setting the height of the over-crossing track at perhaps 10 or 11 cm and the low end at zed, then select this length of track and choose 'Smooth slope' in the menu.
