There are now more than seventy-five (75) BOXCAB pages;
see the main Boxcabs page
and the Boxcabs INDEX.
See the SURVIVOR BOXCAB LOCATIONS MAP.
and the
ROSTER OF SURVIVING ALCo-GE-IR BOXCABS.
See also the Electric Boxcabs page, et seq.
There are now separate pages for each AGEIR or similar surviving boxcab; the redundant material is being removed (very slowly).

I have a long way to go in all this!
Oops! The above had said "are" instead of "were" since I created the boxcab pages but I've long since known the other two are NOT BA&P and the one at Deer Lodge isn't even a real boxcab but a streamliner! I finally got out there on 13-14 Aug 2004 and saw them for myself; much more on all this, with pictures, follows momentarily.

Neil Tice, an engineering consultant specializing in electric motor
controls, was intrigued to read on my "
boxcabl2.html" page about BA&P electric locomotives interfering
with Milwaukee locomotives when they crossed over each other.
His first guess is that there was a ground loop happening.
Electric locos used the rails for the return current and were strapped
to ground to prevent injuries from stray voltage. If the
Milwaukee ran 3000VDC while the BA&P ran 2400VDC, maybe there was
enough difference in the potentials to cause a ground-loop current to
flow between the two.

This theory is perfect. It would be almost impossible to replicate now -- there are so many variables involved -- so there's no way Neil can be proved wrong!Martin Fouts ("Old Fogey") has quite a bit about the BA&P, click HERE to go there.[Couldn't prove it by me, anyway; E. E. was most definitely NOT my forté!]
