I read posts about the rhythm played in the train. I have listened to a large steam engine and a several smaller ones, which I road in the cab once. HOT! The train chuff recommendation seems to fit the large steam engine. If you have a blow/blow draw/draw sound this replicates a very large steam engine, which is really two steam engines under a single long boiler. When going slow the B/B D/D is correct until the engine has gotten up to a higher speed. Then it sounds like one B/D. When slowing down the B/B D/D pattern is correct if the large engine is replicated. The smaller ones have a blow and then a draw, you can google up Union Pacific Challenger on U Tube and listen you will see the B/B D/D. This is a very large steam engine that has two sets of drivers under one boiler. It is articulated in the center to allow the engine to navigate the curves and it is this that has the B/B D/D pattern until it is running ay a high speed. These very large steam engines were produced during the was as some of the loaded trains, two miles or longer, carrying military equipment to a port. The initial sound has a very loud, hard blow/ blow when starting its run but very slow to avoid slipping the driver wheels. It also has the distinct B/B D/D sound when it is slowing down to stop. Also what is the best way to replicate the steam release when the engine stops? Right now I work on the acceleration and declaration portion B/B D/D/ the most. Whistles are no problem. My ? is the note pattern written for the large steam engine.
