Hi Tom:

Yes, all of my AM S-12's have the low-speed worm installed.  I ordered all 
of them direct from AM and during the phone conversation, insured they were 
to be DC w/low speed worm.

Once the engines break free and start to move... they can move along about 
3-4 smph.  That's fair... but not as good as my SHS SW/NW's.  Seeing as my 
little layout will be 90% - 95% switching, I want the best slow speed 
start/creep speeds as is practical.

Perhaps I should also disassemble the trucks/gear towers and make sure all 
is free as possible/etc.  Still can't help but feel that the motor doesn't 
have quite enough torque to effect SHS-like low speed start ups.

Thanks for some input.

You don't say if you have already installed, or got the loco with the
already installed, low speed worms.  It's just one part (at each truck gear
tower) and the speed is reduced by half.  I believe it is technically a
"worm," not a "worm gear."  American Models sells them as

      Low speed worm gear on shaft $4.00 Part # GBWSLS


One would buy them in pairs but I don't know if that's an each price or a
pair price.  Contact American Models directly.
