Hello & Welcome to the Forum

Not a service station set video but an example of an 8206.

The MPC 8206 is a reissue of the PW 665 using that boiler mold and drive train.
Wheel wobble is a known issue with the MPC trains caused by the wheels being drilled off center.

Parts???

These are some of the places you can locate parts for your trains.

There is no specific MPC/Fundimension era trains sub-forum so General Lionel Discussion or the O scale sub-forums
would be as close as we get until the Conductor adds one.

I have an MPC set myself, a 1972 Jersey Central Freight set with an 8303 locomotive.
I've been into trains since the mid 1950's, but they were Marx Trains and the Jersey set started
me collecting Lionel in 2013.
My Lionel is mainly pre-war tinplate with a 1946 221 Dreyfus as my homage to Post War Lionel.

Happy Rails!
