I purchased a used 6-28837 Lionel New Haven TMCC H16-44 TMCC Diesel # 591and I couldn’t find an owner’s manual to solve my problem.
I couldn’t find a switch for TMCC vs. conventional so I’m not sure if there is one or if the engine knows and doesn’t need a switch.
When powered up it takes off at full speed with no control in TMCC mode.
In conventional mode, it’s very slow, unresponsive at times and keeps stopping.
Please let me know where I can find the owner’s manual and if you have any tips.
