Re: MU & Control Systems

Re the older item below, a question I meant to ask at the time was what kind
of control system was fitted to the NSW Class 41 that made it unique for MU
purposes?

I'd guess that it had 110 volt auxiliary electrics (somewhat of a British
standard) and a notched control system with somewhere between 7 and 10
notches.  Does anyone know?

Also, on the subject of BTH-equipped locos, does anyone know what kind of
control system was fitted to the WAGR Y class?  From one of Rod Milne's
articles in a past ARHS Bulletin, I gather that the Y had 110 volt auxiliary
electrics, but nothing was said therein about the control scheme.

Thanks in advance to anyone who can help.

ago when 4102 and 4201 were the only operable diesels. AIUI 42 class can be
driven from the B end but don't have train brake and all throttle notches
available so couldn't be used to haul trains on the loop line. As built the
41 class could MU with another 41 class but nothing else but the MU wiring
had been subsequently removed. The solution we came up with was to install
another control stand in 4102 (we used a hostler control from another 42)
and MU socket. 4102 could then be coupled to the back of 4201 and drive both
locos, albeit with two throttles. It worked OK when tested but I don't know
if it was ever used in practice hauling trains.
