My train repair friend Ed works on mostly older O-gauge trains, but he recently received two Williams locos for servicing. Externally they appear about the same as items in the current Williams/Bachmann catalogue.
Pennsylvania 4656 SD45
Pennsylvania 2361 FM Trainmaster
Both locos have dual DC motors. The frames are very similar except for shell-mounting details. The motors all look the same. The trucks and sideframes are all the same (incorrect appearance for an SD45 !). One unit had traction tires, the other didn't.
These are the first Williams locos we have worked on. The elderly owner reportedly bought them second-hand some time ago, and they obviously haven't been run for ages. They were in filty neglected condition, but Ed cleaned and lubed them.
One loco has an older electronic E-unit which is not working. The board and electronics have dates of 1984. One of the electronic components (transistor TIP125) appears overheated. I removed the E-unit and used a single diode for half-wave rectification to test-run the loco, until we find out whether the owner wants to make additional repairs.
The other loco has a bridge-rectifier (with 1982 date) installed for forward-only operation. There is no clear evidence that an E-unit was previously installed. Did Williams make basic forward-only versions, or was this modified? If they were mine, I would put in small DPDT switches underneath for manual reversing. Or for more money, replacement E-units could be installed ... any recommendations?
Both locos now run well, but forward-only. I like the basic construction of these items, kind of like an Athearn version of O-gauge. No extras, no horns. They are big, near scale I guess, and wouldn't look right with my mostly "conventional" postwar trains.
Any info or comments would be appreciated. I'm a mostly postwar operator in O-gauge and just learning about Williams. I read that Williams started up in 1971 after acquiring some of the postwar Lionel tooling. Is the Williams Trainmaster body a re-run of the postwar Lionel version?
