Utah Frontrunner Commuter Rail acquired old Comet 1 single level railcars to expand their fleet from New Jersey Transit. These Comet 1's are the original EL/NJDOT style with the long doors without traps. They have integrated them with the existing fleet of Bombardier Bi-Level coaches and it has worked quite well from what I can tell.
When looking at older MBTA Commuter Rail pictures you see a lot of pictures of these engines.

Anyone know what they are? Are any still in service or are they all out of service now. The latest date I have seen that showed one of these engines was sometime around 2004 I think. If they are all out of service when did the last one go out of service?
Also, one thing I have noticed too is all older pictures, including control cabs and F40's all show those grates over the windows. What's their purpose?
