This little battery loco looks interesting at its BiN price. It came up as an alternative on the starter set page. Not a make I'm familiar with though and probably a budget mechanism, but might be a useful and cheap way of getting a battery loco to play around with.

The computer-translated description is, shall we say, approximate:
The locomotive is whistling while driving regularly from him. The pipes may leave you by zuklebt the "flute hole" below the moving flap with a strip. This you have to remove the cabinet. The flap itself may not fix it, otherwise goes to the duration broken something.
