The Athearn kit comes powered or dummy. Powered should cost around $25, dummy around $12-15. There are some U28 type features that need to be changed, but nothing really major. The headlight on the nose needs to be removed. The two boxes on the left side, right behind the cab need to come off too. There are two sets of grill vents right in front of the radiator, right behind the "System" in the pic below. You can replace these doors with detail parts or live with the minor discrepency. I chose to live with the discrepency. Out of the box it is 75% or so accurate for the C&O units #3300-3303. With a little help it can be almost 100% accurate.
Below are two pics of real U30C's. Both are
Heacock pics. The U28C kit is good for the one on the
left, the U30C
kit is good for the unit on the right.
