I run 3 rail, high rail wheels, but I have finally found an engine I have been looking for, but it is 2R/3R scale wheels. I understand it will have a fixed pilot (which I don't mind) But what else needs to be done to make it run on my set up? I realize there is a switch for 3R, but does it have the pick up rollers? And will the scale wheels need to be changed? if so what is that process?
Thanks
Bill

The engine should come with the pickup rollers. Have the seller confirm that they have them.
You can replace the scale wheels with the high rail wheels if necessary. Someone on the forum may be willing to do a trade with you.
Here is a link to the MTH Wheels Sets that may help.

Regards,
Four or six axle diesel? I have a couple of diesels with hi-rail wheels if you want to do a swap.
I have an MTH Russian Decapod that is 2/3 There is isolation left and right which is 2 rail. Tender pick-up is designed to use the left and right tender wheels for pickup. The third rail pickup can be added or removed. I have a three rail layout.
Tender switches.
Installed third rail pick-up. Note the isolation bushings between the axle and the wheel.
Wiper isolation detail
There are also isolation bushings/ the truck bearings.
Non isolated side.
Left and right isolation allows for two rail pick-up. Front tender truck/right rail. Rear tender truck/left rail.
The design allowed MTH, at the time, to produce both 2rail and 3rail locomotives with one assembly line. Picture of the Russian Decapod.

Four wheel. I haven't purchased the unit yet...still working that part out, but if I do get it I'll contact you for the swap!
Thanks

I looked at these but am a little confused. The description says:
Convert your Hi-Rail Wheel equipped diesel locomotive power trucks to a Scale Wheeled version. Requires a Proto-Scale 3-2T power truck (sold with 2006 and later models only).
But I want to do just the opposite. I have a two rail scale wheeled unit I want to convert to 3rail hi-rail. Is this what I need?
Yes. That part number is for the Hi-Rail wheel sets. I know the catalog says what you wrote but that is if you have a locomotive where the part number ends in -1 and you want the scale wheels to run on 2 rail track. You have a locomotive that the part number ends in -2 so your locomotive already has the scale wheels. You need the Hi-Rail wheels. I got the information from page 150 of the 2020 Vol 2 catalog.
