Diesel Does It

At the risk of jinxing (is that a word?) tomorrow's commute, I have to say that ever since MARC brought in the diesel engines to tow the trains during this scorching summer, the trains have been running closer to schedule.  According to one conductor I spoke with, they really help in the heat.  And I know the passengers seem to appreciate it as the sense of relief is almost audible when people realize the trains are pulling out on time.  MARC, keep up the good work.
