Broadway Limited Class D Shay

Two weeks ago, I posted on research I did on Class D Shays. The upcoming Broadway Limited Class D was a model I always wanted to get, and I did the research to help me decide which road name I most wanted. I wound up focusng on El Paso Rock Island Route 105:

Here's a picture of the prototype:

As I noted in my previous post, this loco was built to operate on the Alsmogordo & Sacramento Valley branch of the El Paso & Northeastern, where it carried ties for construction of the El Paso-Tucumcari main line. It lasted in this service about three years before it was sold to a Mexican operator.

Broadway Limited appears to have followed Pacific Fast Mail's 1960s philosophy, which was to issue a "generic" model of any particular prototype with features that don't match any one individual locomotive. Thus every BLI model has acetylene style headlights, but also an electric generator. The prototypes were built over a relatively short time period before electric headlights were in general use, and photos suggest that at least some never had electric headlights. Nevertheless, the sound features include an electric generator whine to power the acetylene headlight.

However, in many cases, there are so few prototype photos of these locomotives that it's very difficult to determine exactly what features individual locos had at particular times, and for several prototypes, there's no information on exactly where and in what service they operated.

I chose the El Paso Rock Island Route prototype, even though the model features least resemble the actual loco in the prototype photo, because it matches the southwest area of some of my layout scenery, and because I have some ties to New Mexico. As a Boy Scout, I went to the Philmont Scout Ranch, and in later years I traveled through several times, as well as working for a client in Albuquerque, so the loco is a souvenir as much as anything.

I'm still figuring out the best way to tweak the sound to get the best results. I've ridden behind Shays on the Roaring Camp & Big Trees and the Georgetown Leep Railroad, and while the sound has the correct triplet cadence of a three-cylinder loco, I think the chuff rate is too slow, and the bark of the exhaust isn't as muffled as on the prototype. I'm going to turn the volume down.
