JERSEY MIKE – YOU ARE WRONG!!!!!!
You can’t imagine how long I have been waiting to do that
Actually, Mike is almost right. The theory of the single car MU's not properly sending a zero pulse to the rail behind it is correct in most situations on Amtrak. The same also applies to single AEM-7's, HHP-8's, ALP-44's and I think ALP-46's.
If my memory serves me correct, SEPTA has upgraded the cab signal system on their own railroad to allow for the operation of these engines and single car MU's without protection to the rear.
Most of Amtrak's railroad does not permit this, however there are a few sections between the upper level of 30th Street and Valley Interlocking (where the R6's leave the Harrisburg line) where Amtrak has upgraded the cab signal system to enable single car MU operation and single lite electric locomotives.
