I visited the Nantucket Railroad display yesterday (in the Whaling Museum in Nantucket, Mass.) to change the engines on the display. The display is a 28' long model of the Nantucket Railroad as it looked in 1910.
Since it was built in 2009 the display has been running several On30 Bachmann Forney's with sound. I selected this engine type because it looked similar to the 3-foot Mason Bogey-type engine that the railroad used. The Railroad also used an American-type engine but the models available do not, as yet, have sound. The Bachmann Forney's had a problem keeping the trailing trucks on the rail even when running on straight track.
I replaced the Forneys with the new Bachmann 0-4-2 Porter with sound. I bought two of these engines and painted and lettered them for Nantucket.
Yesterday's trial was a success. The engines pulled two passenger cars back and forth without hesitation, and performed all the stop and start tricks I built into the DC circuitry. The sound from these engine is loud enough to get attention in a crowded room and sounds close to real.
All in all it was a successful day. It'll be interesting to see how long these engines last in continuous service.
