Any advice on a steam locomotive, new that will not retain Id number. I can program locomotive on a test /program track which is connected to same TIU but when I move to mainline engine is lost, 'can't be found', ''not on track'. It shows in the remote but cannot start up. No problem with any other PS 2 or 3 locomotive. Engine connection doesn't seem to be able to communicate to TIU. If on the mainline it sometimes comes up in conventional mode.
Remote has been reset, TIU has been reset, TIU and remote are on same channel. All Tiu outputs work, no fuses are burned out in TIU.
Model 30-1862-1, 0-6-0, custom THB from EZ Catch
