I got this off the ESPEE Modelers Archive.
Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California Turned 84 in July, aging is definitely not for wimps.
I have a bunch of these, from Tichy...
The orange one, left-most, below, of the three that are together, is definitely from the '50s, as I bought it in the '50s, as part of a Revell kit for a fueling and sanding facility...
This black & yellow one, at the bumper, was a cast-metal kit, but I don't recall the manufacturer...
...I guess if I had found this photo earlier, I could've skipped the previous ones.

GHQ, custom-finishing, shapeways, and JL innovative make different speeders. Maybe one of those matches?

I can't specifically say the SP used them but the Fairmount M-19 or MT-14 was a common machine in the era. Durango Press makes, or at least did at one time, a decent white-metal kit of one:

If you can find one, there are three different speeders plus trailers in this Durango kit:

Walthers includes a rather rudimentary one with their trackside structures kit. It's OK for a background model but not much else.

Good Luck, Ed
I'm trying to hunt down the particular types of speeders that were used by Southern Pacific in the 1950s. And if there are HO models available. Google Images seems thin or ambiguous with the SP 50s parameters.
Thanks,
John
