Great pictures! I like #502! Anyway the longer she sits like that, the worse off she'll get. I believe you said all work on 502 gets done at MMC, but someone needs to just make a desicion and get #502 brought into the shops down there and get her back up and running again.
Not that I know alot about the situation, but if you need a work engine and you have one, it just needs a bit of repair and instead you lease one. Waste of money if you ask me. They spent all that time getting #502 back up again and then had it transported down to river line (took a week) and one small problem and they just let her sit like that. Why they just don't make a call and in this instance sub-contract out the work, just so she can be up and running again. In this instance, too much work getting her back to MMC... then getting her fixed up and then back to river line again. At least one thing... at least #502 is still on active roster.
