I am converting a large-scale 3-truck Shay to battery R/C using a QSI Titan Magnum power/sound decoder.

This decoder has stereo sound outputs, allowing sounds to be 'positioned', i.e. appear to be coming from different locations on the locomotive.

I think it would be awesome to have chuff sounds coming from the stack rather than from the tender, where the main speaker is located.

I'm using the diamond stack (following the Cass Scenic Railroad's prototype practice), which could (theoretically) hold a small round speker in the diamond-shaped part of the stack (I don't use the smoke generator).

The manual shows the stack is made of seperate top and bottom cones, but they don't look like they can be seperated.

Does anyone know whether they are permanently fused together, or can they be seperated somehow??

Thanks,

I am converting a large-scale 3-truck Shay to battery R/C using a QSI Titan Magnum power/sound decoder.

This decoder has its own firebox flicker function which can drive the red and yellow LEDs seperately, just like the original Bachmann board does. However, the LEDs must be connected as common anode configuration, instead of the common cathode configuration that Bachmann provides.

I need to access the LED boards to reverse the LEDs. The ashpan board is easy to get to, but can anyone tell me the easiest way to get to the firebox LED board?

Thanks, JD!

I suspected the flat car w/ logs was 1:22.5, but since I haven't yet bought any, I wasn't sure.

I have a couple of the "1:20.3 20-foot" flat cars which look reasoably good, but just like the comments on the box cars, they're really small! I don't think I want to get any more.

I also have several of the skeleton cars, but wasn't sure of the scale.

I'll probably go with the 1:22.5 flat w/ logs, since I'm doing a model of the Greenbrier Cheat & Elk (Cass Scenic RR) which used flat cars w/ rails on top for a Barnhart-type loader. I can't afford a large inventory of the Spectrum cars!

About a year ago, there was a thread about box car sizes (953XX, 933XX, 880XX) which I found to be very enlightening.

I'd like to ask the same question about the 2 current log car models - 98470 (flat car w/ logs) and 98490 (skeleton log car). I think I recall once seeing that the skeleton car is 1:20.3 which I'd like to verify, but I'm really interested in the flat car w/ logs (98470).

Is it also 1:20.3 or is it 1:22.5?

Thanks,
