Lionel TMCC PRR M1A

That's for "Rail" sounds or "Signal" sounds.

Railsounds is the full package i.e. chuff, crewtalk etc.

Signal sounds is just whistle and bell.

If your running tmcc a battery is not necessary unless your experiencing sound dropouts over turnouts.

The 9v battery option is for that I just mentioned and to keep the sounds on during g direction changes if you were operating it conventionally.

Thanks a lot.  The engine is incredible and that coast to coast tender is a monster.  I just wanted to make sure I was getting the most out of the incredible fatboy speakers.

Thanks again.....have a great day!!

Agrazprr,

     The TMCC M1a was also one of my first command control scale engines. You are correct the sounds are terrific. Mine has been upgraded to four chuffs per revolution, GRR Super Cuff board and in my opinion holds its own to the Legacy versions. The upgrades were down by Alex M

John,

Thanks for the feedback, four chuffs per revolution sounds like a great idea.  Does Alex M still do that install.  I'd like to have that done as well.

Please advise on how to contact Alex.

Thanks,

Tony G

I’m sure he does. Go to his profile for his email. Enjoy.
