Been talked about forever, since about 2006, official product announcement in 2014, so 18 years in gestation, and 10 years after formal announcement !!! Becoming available in 2023 and 2024.

To their credit, apparently AML was very responsive to some reviewers of the prototypes. I did help give input, which was eventually addressed.

The motor blocks have steel worms, and nylon worm gears, nice large ball bearings

Power pickup is by wipers on the axles like USAT diesels

First Release: (only from RLD Hobbies)

The first sold were actually from RLD Hobbies. Robby was smart enough to realize the endless delays to market were going to continue with the added delays to get the internal wiring to accept a decoder that is NOT standard, and NOT common in the USA. There were many excuses for the delay, but still a big delay.

Robby managed to order several road names that had NO electronics in them, period. No speaker, no lights, no circuit boards, just wires from the trucks for the motors and track pickup.

Colin Camarillo got one and I've got a page on his adventures.

Second Release: (first real production)

The second release has a socket apparently to accommodate an ESU Loksound 5 XL decoder, but they still have not been delivered with the decoder. My friends Ted and R.J. have gotten them, and there are a number of issues, most importantly there is NO documentation on the connections, NO screw terminals, and NO standard socket like the Aristo or the Bachman-enhanced version of the Aristo socket.

hoo boy! Personally, I'm displeased with the result. I understand how AML got here, but cannot agree. It's an unholy mess attempting you to never modify your loco or buy an ESU Locsound decoder.
