I have a pair of PS2 F3 locomotives that will each run on their own, that I have run in lash up for years. After a TIU change from a Rev I.3 to a Rev I, it will not lash up. Each loco runs fine individually but as a lash up it says engine not on track. I have deleted the lash up and then both locos and then re added the locos. They each run and function perfectly but when creating a lash up I still get the dreaded Engine not on track message. Any thoughts?
