I enjoy Carlos' pictures more and more every week and think it is especially kind of him to constantly give credit to the other shop employees. It seems to me they are ALL doing a great job.
Apparently the problems that the two locomotives had were not out of the ordinary and were solved quickly.
This brings up a point. Carlos shows pictures of 488 parts being worked on. Is it realistic to think that it will be running in July. That would certainly take a lot of pressure off 484 and 487.
