Narrative:

Maintenance needed to run up the engine; because pressure relief pin on #1 engine had popped and they replaced it. The passengers were already boarded and we decided to have me run it up rather than take everyone off. I got the sign to start #1 and we proceeded to do the maintenance check. This is when a tug pulling 2 bag carts drove past the rear of the aircraft. It blew 1 cart over and tipped 1 upon 2 wheels; and blew a glass window out on the tug. No injuries were reported and I advised ramp to clean up the glass. I believe there are a couple of reasons: 1) we had no one behind us watching/stopping tug traffic; ground was stopping the aircraft. 2) the tug driver was not paying attention.
