Reply to "Servicing Newly purchased Lionel L3A Mohawk & Vanderbilt"

I have an 18064.

This model was known for being fitted with a weak ACDR motor controller from the factory, resulting in low top speed and poor pulling power:

A replacement unit was offered through Lionel Parts, No. 691-PCB1-021, which was intended to fix both problems. With it installed high speed performance is much better.

Even so several techs on this forum prefer to modify the 18064 even more radically by removing it's AC-powered Pulmor motor and replacing it with a DC can motor and a DC TMCC controller like an ERR Cruise Commander to improve its low speed performance and smoothness as well.

You can choose either one and be happy depending upon what kind of performance you're looking for.

Personally I'm fine with the ACDR upgrade.

Mike
