Mindstorms RCX Controlled Train

Can you control a train using a built in RCX module from a Mindstorms set? Yes, and this is my first attempt at it. I've built the RCX into a boxcar based on the one from set #4563. It's slightly taller than a standard boxcar but only by a few plates so it's not too noticeable.

So far all I've used it for is to control a train so that I can start and stop it with a button, next I need to add sensors on the track so that I can have an automated train.

These pictures are taken with a video camera so sorry about the fuzziness.

Here it is with the side off.

With the side on, a 14x6 plate instead of the standard doors.

And here is a shot of the end showing the transparent red bricks that allow IR communication without removing the RCX.
