The prototype measured a locomotives performance, such as tractive effert, speed, power, etc.

Mike.

EDIT:  From the ad in Walthers for their car, it does measure pulling power, which is the tractive effert.

It sounds like you are asking about the prototype of the Walthers dynamometer car.

 

This one looks strikingly similar:

As you can see, it is owned by Alco.  The photo was probably taken about 1965, and the location might be Hillyard WA.  It was undoubtedly built by Alco.

 

This one also looks strikingly similar:

 

It was built by the Burlington itself in 1930.  Note that the cupola doesn't quite match the Walthers one, which gets me thinking Walthers might have done a copy of the Alco version.  And the Burlington one looks so close that it gets me thinking they might have sorta copied the Alco one.

Another railroad might have bought a copy of the Alco.  Most of the photos I see of this kind of car seem to show every one different, though.

Yea, the Walthers car seems to be a little of both.

Not sure if this is allowed, but Geoff Bunza did a write up on one he made digital, with lots of cool pictures.

EDIT: Never mind, the link didn't work.

  I suspect that Alco bought it 'used'.   It would have been used for steam in 1930.

Here's a model I found online.

I figure it's a kitbash.

A bit more research:

 

model:

 

 

real one:

 

 

 

The car was built for NKP in 1924 or 1927 by Standard Steel Car.  As Jim said, it was apparently (I use that word because I haven't found info on the Alco times) transferred to Alco.  And Alco gave it to the Mad River & NKP Railroad Museum.

So.  The model is good for the Alco and NKP versions.  And anyone else who did a copy.  As you can see by looking at the photo of the Burlington car, there were some that were awfully close.  A person might wonder if the Burlington car could be properly done by using a caboose cupola.  I'd wanna see a right side photo before hacking up a model, though.

NWP SWP

Looks an awful lot like one of those MDC kitbash things, though I can't find anything on them doing a dynamometer car.  So I'll assume it's a do-it-yerself.

It does have the flavor of a dyno car, though.  Only thing is it would have been better to have the cupola moved over to the left.  Still.  Pretty darn neat, though.
