with 2 boilers at less than 10 pressure connected to a large steam wheel piston (both sides of course) and 3 large steam wheels the locomotive cant reach speeds above walking. this locomotive is 11.5 thousand kg so it is definitely heavy enough, the wheels slip at any regulator value (variable valve value) and at nearly any pressure everything has been verified to be connected properly. is this intended? (i hope not) im pretty positive this is not and if it is could you explain why and how it is intended (if at all) how we can get higher speeds with the large steam wheel parts? this issue is simple to recreate, simply place 3 large steam piston wheels with their respective large piston and apply steam pressure through a variable valve, it is easy and quite obvious when the issue happens.
