Clark Propst started this thread by asking: "I realize both the GN and NP had steel box cars with wood sides. <<snip>> What are the major differences between the GN and NP cars? roofs, ends, doors and

From Clark Probst: I'm tardy joining in this discussion, but it's clear both from photos and from the NP diagram book that the NP 9480-9999 series box cars, built by Pacific Car & Foundry in 1939,

<snip> Yup, Tom, we're out here! I can't speak for Earl, of course, but I'm sure he's busy dealing with the new property he acquired a month ago. As for me, well, I'm just continually falling

Just out of curiosity, if the molds are made of cast steel, and you are pouring molten iron into them, which should have the same melting point, what keeps the inner walls of the molds from melting

I understand that the GN car is not a '37 car, just looks like one. So, it is possible that the NP car is? Unfortunately, I couldn't make Ben's link work. I have built Sunshine models of the GN car,

The GN cars are tall 1925 ARA box cars. While I have not studied the NP cars, I would be that they are double sheathed versions of the 1937 AAR box cars. That certainly fits with the visible

I've uploaded a side-by-side of the cars in question on the STMPH group website which should answer some of the questions raised about these cars. I'll post a more comprehensive answer after I get

I believe two different NP cars are being discussed. There was a DS car built in the 20s that is modeled by a Sunshine kit which sounds like the one described by Manfred. There is also a DS car

I have been looking for years for a photo of the elusive single gondola car in PRR class G21 to no avail. Does anyone know of a link or source for such a photo? I have a diagram for the car and a

Clark, I am waiting for Earl Tuson or Jeff English to weigh in on this issue. I had once assumed that what the St. Cloud car shops on the GN had accomplished the NP shops at Brainerd, Minnesota,

Ed- Could you provide some links or be a little more specific....there are many choices on the "Rivers of Steel" home page. Thanks, Charlie Vlk

A well-deserved "thank you" to everyone who submitted ORER information! The March issue of TKM will hit the streets this week. Ben Hom

Garrett; Could that PS-0 be an ex-B&LE car? If you have not talked to him, Scott Schaller of Trackside Photos has a list of great drawings and such for various USS allied roads. He recently listed

I'm in the middle of building one of these Pacemaker cars, and need to know what modifications were made to the brakes on these cars. In a Col. Chet McCoid photo of car #174226, it looks like
