Cab inside.

I've been doing some research on locomotive cabs, because it dawned on me recently that Growler 1 is going to have pretty huge windows so it needs interior detailing. It seems I've got to make the cab look something like this, which is a DB class 290. It even has a computer console.

Fortunately a 290 is a tad bigger than the DB class 399 that my model is based on, and the controls are more complex, for example I can probably dispense with the main computer- it's from DB's timetable system, which an NG loco isn't likely to need. On the other hand the basic controls for the power and brakes are largely similar, and they're going to be very small in 7mm scale.

Hmm...
