In the last weeks whenever we've had hung visitors to our property I've taken them into the shop to look at the train. The visit includes climbing into the train engine cab and trying out the whistle and bell - much to the delight of the kids. While I also took delight in the loud noises I was watching how the kids used the equipment, taking mental notes on how to improve things. The kids couldn't resist twisting the various taps (as intended). With the operating controls of the train on the right side the bell cord was on wrong side for the kids to pull.
