All Non-brass AZL locomotives with part numbers that have 5 digits before the dash (AZL 12345-X) are rated for a maximum of 12 volts DC.
Brass locomotives, or earlier locomotives with 4 digit part numbers (AZL 1234-Y) have a maximum voltage of between 8 VDC and 12 VDC - please refer to the original packaging for your particular maximum voltage.
Rob, It's good that you have published this information: it's long overdue. But is it really as simple as stated? I thought the first run RDCs were built with a non-12VDC motor. I do have to take exception to the "refer to the original packaging..." I have the AC-12, original GP7 and first run RDCs and none of them had a maximum voltage specified.
FYI, here is an excerpt from a note included in my (what now appears to be) early run CNR SD75I, part number 6103. (there was no Dash anywhere; the road number is 5681.)
"The Faulhaber motor is rated to 8volts. Do not operate motor past 8volts. If you use a transformer which has a stronger output than 8volts, you must measure the current with a voltmeter to establish the 8volts point on the transformer."
I'm very glad this post was made, as I was half dismissing this note since I'd heard "AZL locos don't care if its 12v" preached ever since I got to Z.
