IRM Diesel days are coming up. July 21 and 22 will have lots of diesels as listed by Jamie below as well as freights and caboose trains. So come for a visit if you can.
I think the video of the alligator start up was posted last year, but it’s worth seeing again.

Diesel Days, July 21st and 22nd, 2012
We'll kick off each day at 10:00am with normal operations, the heavyweight coach train pulled by BN9908 and BN3; the Nebraska Zephyr pulled by CBQ 9911A; and a four car caboose train pulled by CBQ 9255, and the CNW bilevels pulled by CNW 411. Later in the day we'll have a few freight train run-bys with different power each time. We may change the power on the heavyweight coach train and the caboose train after the parade.

The Parade of Power will begin around 1:00pm-1:30pm and will include the equipment listed below, but not necessarily in this order. Similar to last year, we will again have the BN 5383 under load from CNW 6847 heading East, and the CNW 6847 under load from BN 5383 heading West. The same drill for the CBQ 504 under load from SP 1518 heading East, and SP 1518 under load from CBQ 504 heading West. They will not stop in front of the depot as the other trains normally do.

What was for me the interesting video; sound is clearer, and the unit has "chunky" exhaust (looks like leaves were in the exhaust system):
