Thanks to John Regan for this information, also to Bruce
Bellingham for his comments on the EE/GM MU operations.
John, I'd appreciate having a copy of your operating
instructions. Either scanned or copied will work for me - I'll go along
with what any other takers prefer. (Are we supposed to do these kind of
transactions off-list?)
Cheers,
Steve Palmano

Greetings
Perhaps now might be a good time to explain how the GM's
were coupled to the EE and Mitsubishi locos for MU operation.

I have my old Loco Staff operating Instruction book here
with all the brake diagrams etc so if anyone wants copies of this stuff let me
know and I will either photocopy it and send it or scan it.
Cheers
John

All of the above assumes that compatibility of the basic engine power
output control scheme is a necessary, but not sufficient condition for MU
compatibility. Strictly speaking, even this is not true as arrangements for
interworking amongst locos with fundamentally different control schemes have
been devised. The coupling of 74 volt, 8 notch EMDs to 110 volt, 10 notch
EEs in New Zealand has already been mentioned by John Regan in this thread,
although I've never seen an explanation as to how it was achieved. I think,
though, that this was a one-way system in that the specially equipped EMDs
could control the EEs, but not the other way around. Another example is the
BR Southern Region scheme that allowed bidrectional control between EMU 4
notch and diesel air throttle systems. In the USA, UP MU'd standard, 8 notch
diesel electrics with gas turbines that had 20 notch controllers, whilst (I
think) that SP MU'd air throttle Kraus-Maffei diesel hydraulics with
standard diesel electrics, and Milwaukee controlled standard diesels from
the multinotch "Little Joe" electrics. And of course, in Australia, QR had
leading EMDs controlling mid-train air throttle EEs via Locotrol wagons.
With the exception of the BR system, I've never seen technical descriptions
of any of the above in railfan-accessible publications, and even with the BR
system, some aspects remain sketchy.
