Lionel 18025 Texas & Pacific, can it be converted to TMCC?

I think with enough money, anything can be converted

Yes.

This is the NYC Mohawk with the T&P paint job, is it not? Very straightforward models.

An ERR AC Commander (this locos had the AC Pullmor motor) will do the job, and the plastic coal load that I believe these had will make the antenna a 60-second installation.

Railsounds and Electrocoupler also available from ERR if desired. No Cruise on an AC

motor, but these are pretty properly-geared locos, and are not zoom-zoom toys. 

Thank You!!
