That blue Beyer-Peacock in the middle of the video wants its timing adjusted quite badly, doesn't it?
I think its timing has already been adjusted badly!
It is the steam-outline electric locos that puzzle me. Now, I know nothing about how the sound is done on these but the "chuffs" don't appear to be tied to the wheel revolutions. Is that correct? On the Gauge 3 layout there is a delightful 0-4-0ST which appears on this (and other) video to have anything between two and eight chuffs per wheel revolution, apparently dependent on speed, when it should always be a constant four. As I said, I know nothing about this stuff so is it really difficult to set up and get right?
That "coasting" feature really adds to realism! It makes the loco seem much smoother, as hough it's gliding along the way a real steamer does rather than grinding down the tracks the way a lot of electric powered models seem to.
