Andy,
Both 4223 and 4228 were outside along side of the original shop on Friday. I have seen people working on 4223 occasionally when viewed from the parking lot, but I have no idea when, or if, these two locomotives will be going to Maine. 4223 still does not have number boards in the front nor all of its headlights.
I have not seen the 18 in a while, so can't comment on its cleanliness or lack there of. It is usually out on the road when I sneak over there at lunch time. 4228 is fired up fairly regularly to move equipment around the shop and, if they need two crews, it is used on freight on the original M&E. Lacking cab signals, it does not venture out onto NJT except in the company of 18.
