Some pure speculation. --- Amtrak has had many loco fasilures from Perryville - WASH in the last few months. There are not enough failures to reliably say that this section is having a significant # of failures but someone needs to look at this. The NH - BOS section does not seem to have even 1/4 the failures that are occurring here.
What could be the causes.
!. Low voltage or wide swings in voltage ?
2. The use of 25 Hz instead of 60 Hz ?
3. CAT sags causing interruptions to the locos ?
4. Present heat ?
