Hello Casey,
Unfortunately, virtually none. The chassis needs to be heavily milled out in order to be fitted even with some small decoder. Additionally, the characteristics of the old 3-pole brushed motor used in this model are not the best in class even among brushed motors - this one is very noisy and consumes quite a high current. I would therefore recommend at least 1A decoder - just in order to stay on the safe side with this loco (of course, if you find a way to install it there).
Regards,
Alex

Its not that difficult , just need to remove some of the chassis with a dremeland solder the wires to the motor and lights. I am running a A-B-A consist in UP, unfortunately the B is not powered. And the unpowered shells doesnt fit onto the powered chassis without grinding die B shell

They are noisy, from there the name coffee grinders, but thet are strong pullers. Only thing they run way faster than AZL locos or MTL GP' and SD's

But worse, the power it draws. A perfect motor ‘might’ draw 100ma, if you dream. Many are 250 ma. A DCC decoder can handle it, but its not recommend.
For DC, the Rokuhan won’t but some hand-helds will and the “Table Top” certainly will.
They tend to dance the wobble of an abandoned spur.
They will ‘run over fingers’ having great pulling power.

Actually there is a decoder that will fit with out having to mill the chassis The ESU LokPilot micro but its only a 0.75A decoder. Read scanrail's post above. With that said I ran a pair of the MTL F7 with the ESU LokPilot micro decoders for a hour or so at our last show with out any issues. Well actually that's a lie i did have trouble with the MTL Ringling Bro's passenger cars that they were pulling constantly derailing. So after about a hour i just parked the whole Circus Train on a siding. But that had nothing to do with the locos or the decoder.   Another option would be to swap in a Can Motor that draws less. My MTL F7 Can Motor Upgrade is posted over on TrainBoard |
