484 and 487 still had the original style of solid wood doors on them and will get new ones this winter. I am not certain when they were built but I believe they date to the D&RGW days. 488 and 489 have composite doors with a steel outer shell lined with wood. We built these back in the early 80s as I recall. They are still in decent shape although they don't really fit as well as they should and they are starting to show their age. My plan is to use the spare set on 489 next winter. The cab will be off for the 1472 day inspection and I hope to get some other repairs made on it then.
