Here is a video of my venture into 1:20 scale. The Shay, boxcar, and caboose are as yet painted, they get decals and weathering next.


This is the inaugural run of all three, I figured a little shakedown was in order prior to decaling and weathering. The Shay had run a few hours on test rollers and been lubed twice. Then it developed problems with the center truck, That truck would just not start turning the wheels until it got to half throttle. I tore it apart twice, cleaned and re-lubricated it, added wiring to by[pass the spring contacts on the mounting pivot, (which didn't seen to help) and finally taped on the motor shaft while it was running at full speed. Now it seems to start at a lower voltage, so I figured I'd try it on real track instead of rollers.


This is 6 short clips out of almost two hours of video, Please pay attention to the starting and stopping. How does it compare to other Bachmann Shays?

I also included a full speed run pass, Does the speed seem about right for the top end on a shay?The engine seems fairly capable, I did quite a few coupling and uncoupling moves, I don;t think it pulls as well as my LGB Mikado, but it is more than strong enough for the few cars I plan for it. The 1:20 scale Bachmann boxcar is really nice. For now I'm using a Bachmann 1:22 scale caboose until I build a Hartford Kit caboose to go with the Shay or upcoming Kay.

Thanks guys,


The high speed run seems to work out to about  20 scale MPH, I think. That was at full throttle with the Decoder set so the max motor voltage was at 33% of track voltage.


Looks like the Bachmann model should have been geared down some more.


I'll try setting vmax to 25%


Sorry about the confusion over the sound. Those were the K27 sounds loaded into the Shay,


I was so intent on the center gearbox problem that i forgot to reload the shay sounds into the sound card.


Those were actually the sounds I was working on for my new ( as yet, not arrived) Bachmann K27.


And yes, I still have work to do on those sounds, The bell is not only disgusting, but it is a mechanical bell sound, not a hand operated bell sound. It will be changed ( and a lot of other sounds) before that file gets loaded into the Kay, When I reload the Shay sounds into the Shay and have both the Kay and Shay running I'll make another video so you can hear them together and perhaps give me some more hints about the sound.

In a few weeks I'll be able to do some accurate speed measurements and set max speed correctly, For now I was just  wondering how close I was getting. Thanks for letting me know it is too fast.


So, Anyone know just how fast the real Shay and K27 run?


That video was shot with the Max speed setting in the Decoder set to 33% of track voltage, which should be applying about 1/3 of 20 volts to the motor, about 6.6 volts.


BTW, At speed step 1 it takes the Shay about 7.5 seconds to move one tie.


I'm not entirely happy with the smoothness of the Shay's slowest speed, but with a little more run time and some more tweaking of the decoder, and I think I will be very pleased.


Still a lot of work to do on it, get the Shay sounds reinstalled, Decals for the ALLY, maybe a little rust, some tools and a toolbox.


With the Kay's gear-head motor, I think Bachmann may have finally made a loco I could love. I'm looking forward to seeing just how smooth the Kay will run. Just hope the wheels are round.


Another video is in the works, Maybe next weekend I'll have the Kay and Shay both running.

Very nice tom.
Yea, rub it in, Only took you a couple days! 
I wold have loved to be able to just plop it down and run it like most of my big LGB locos, but mine came without the sound or DCC. The extra 200 bucks was just a waste. Had I known they did not have enough sound equipped Shays to fill my order I would have never ordered the Shay.. Bachmann refuses to make it right, apparently they can't because they didn't order enough sound cards. 

Took me a month to hand wire in a decoder and sound card, but now that it is almost done, I rather pleased with the loco. I would have gotten several had I been able to without all the aggravation of trying to deal with Bachmann. 
I put Kadees on mine too, I've done a few switching operations with it. The Shay is plenty smooth enough for delayed uncoupling. 

On your Shay, do the headlights dim as advertised for the Tsunami? Does the flicker effect intensify as advertised for the Tsunami? How did you letter the Shay? That is my next step.
