These were the New York Central System's variation on the 1905 Common Design hopper, the primary differences being the pressed shapes used for the side and end sills, and the three end sheet supports.

No unaffiliated railroads as such, but there were a few industrial piggyback orders. David Thompson

1951 and later. Some of these also got new ends, so check those photos. David Thompson

Not much. Edson has it existing 1902-03 before being absorbed into B&O. Probably standard gauge, and more likely than not set up with the intent of having B&O buy it. David Thompson

Newburgh & South Shore comes to mind, and there were a variety of other small roads and industrial users that had H21a or H25 clones. There were some other designs of increasing differences, Lehigh Va

Depending on how much detail you're after, Railway Age ran some truck drawings in the April 5, 1918 issue, including the not-used USRA archbar design. David Thompson

SAL AF-1 11000-11699 P-S Bessemer 3/40 SAL AF-2 11700-11999 and 22000-22199 P-S Bessemer 4/42. Major difference between the two was the stiffening ribs on the roof sheets for the AF-2. See RPC #13 for

The Virginian composite box cars (Bx-10 and -11) had steel plate ends with three vertical ribs. David Thompson

I like the d20 method. If you roll a 20, pull the aluminum reefer out of its box, put it on the layout for that session, then put it back in the box at the end of the day. Next time you roll a 20, pul

None of them, really. The H6 falls outside of the dimensional envelopes of all three. The Bowser GLa is a good starting point for an H3, the Accurail USRA twin is good for H9 and 10, and the Athearn b

Is this a comprehensive list of their holdings? The car I'm looking for wasn't included in the index. David Thompson

Class Ara, the sample box that PRR built in 1917. David Thompson

Just a note that the abbreviation might not have been for a C&O location. Cars did get reweighed offline every so often, though it generally was uncommon. David Thompson

Code 110 wheelsets are sold as "scale" (versus Flyer barrels) in S. I find it amusing that P:64 wheels are code 87, while P:87 wheels are code 64. The true scale wheels do look much better, but then y

X was the design which succeeded the frameless Van Dyke tanks, not conversions of them. One or the other of the famous narrow-gauge tanks can be converted back to a standard gauge X without too much t

IIRC the 156# stuff was only used on the line from Pittsburgh up to the Lake Erie ore docks, and maybe a handful of other small locations. The rest of the main system was the usual 120-130# rail that

One could "de-spread" the sills on the Blackstone model and add the bolster supports to go back to the standard gauge version. David Thompson

In the interest of modeling these cars, does anyone know of a good source of car numbers for 6k Vs and Xs in, say, the late '40s? David Thompson

LV 25000s were the typical anthracite fishbelly twin, but this one either got new sides somewhere along the way or got renumbered from the 20501-21000 series. Built in the '30s either way. David Thomp
