Guys;

The X29D are a very complicated class. The X29D had a lot of little detail differences than have been generally discussed, either for the kit research, or in the RPCyc article, IIRC. While some of the standard details have been talked out, there are still things like the "high tackboard/low tackboard" discussion that never made it to press. The brake equipment story also does not have a final answer, but some interesting leads.

I am not sure I understand your question, Mike. Series 25501-26500 were indeed the highest numbered block, but were all produced first, and in sequence, as-built, with stenciling stating "BLT. 8 24" (rebuilt 1952), not "rebuilt" as in the later series. They do all appear to have been numbered upwards in each series.

There is also the issue of which cars got the "Don't Stand Me Still" logo, and in what color.

If you're interested, I can dig up my "to-date" data package.

Hello Group!

There was a difference, a distinctive one, between early and late production X29D cars.

The first group of 1000 cars (25501-26500, 9/1952-4/1953) were built with the "short taper" 1-3-4 ID ends. Groups two and three (23601-25500, 6/1955-1/1956 and 22301-23500, 1/1956-7/1956, 1900 and 1200 cars respectively, were made with the "long taper" 1-3-4 ID ends. The earlier noted F&C model covers the first block of cars. Not mentioned is the Wright Trak model which captured that difference with a nicely done model of the newer two blocks. These X29D distinctions are well covered in RP CYC 26.

I have come to suspect (maybe I read it) that at least the last block, perhaps all three blocks, were numbered downward, that is, newer cars were assigned lower numbers. Can anyone verify this?

Regards to all----Mike Schleigh

Hi John,


John Golden here in St. Louis.  How's it going?  I'm preparing a fairly extensive presentation on ACL Box Cars for Naperville and other RPM events.  I'm working with Buddy and Larry Goolsby on it.  I'd appreciate seeing your information.  Would you mind sending it to me at Golden1014@..., please?  I'll send you a copy of the presentation.  I'm about halfway done with it--got some great photos from all around.  I can send you an in-progress copy if you'd like--just let me know.

Re: B&O container chassis question

riverman_vt@...
 

Tim,

     What would be so surprising about that? The Boston & Maine was offering "Freightainer"
service in 1928 with containers about twice the size of those the Youngstown offered some
ten years later. It was given up from a lack of demand and the fact that no other reailroads
really seemed interested at that time.

Cordially, Don Valetnine

Re: B&O container chassis question

rwitt_2000
 

Tim,

Yes it is. In the late 1950s, the B&O and the MP instituted a special Baltimore to St. Louis COFC service using custom designed containers and special flat cars to carry them.

Part of the need for COFC was the low clearances on the B&O Parkerburg sub: Grafton to Parkersburg.

It was short lived service because the B&O day-lighted all the tunnels by the early 1960s allowing regular TOFC traffic.

There are some photos on the web for the MP equipment. I will look for the link. There were some articles published in the trade press when the service started.

An side the B&O recovered the relatively new underframes applied in ~1955 to the rebuilt M-15 wagon-top boxcars and converted some to TOFCEE and COFC service.

Regards,

Bob Witt


Re: B&O container chassis question

Tim:

 

This is not a standard container chassis, not there is no provision for locking/attaching the container to the chassis.  This is for a special unit that attaches to it.  Not for regular COFC service.

Reposted the file with corrections provided by the ACL/SAL group (Buddy Hill), added an IH column for the appropriate cars & corrected formatting errors.  This last issue was created when I converted the file from XLSX to XLS format.  If anyone has to have XLS format, let me know off-group and I will see if I can correct the formatting problems.  Again, let me know if you find any other errors.

Re: KCS #20820 and 20834 missing from 1949 ORER?

mopacfirst
 

This is probably a pointless note, but since I have six or eight of the Life-Like original kits I went to check if any were KCS.  Sorry to report none are, they're mostly NYC and SP.  Still, there are more of them here than I am ever likely to need.

PS they strip pretty well.

Re: KCS 20800, etc.

Garth Groff <sarahsan@...>
 

Eric and Bill:

Interesting mystery, and it leads to more questions. It doesn't appear that those missing numbers were ever filled. It looks like the Walthers people made an error <SHOCK!> . . . something I'm sure that almost never happens.

In my 1958 ORER the KCS 20800 series is broken into 20800-20801 and 20802-20809. The former pair are now XAP boxcars covered under note "S" which says they are equipped with special racks for loading Chevrolet front axles, designated as Circle 3 [?] loading. The "3" is partly blatzed out in my photocopy, so I'm not 100% sure of the wording. 20802-20809 remain as XM boxcars. There are no other cars with a 50' 6" IL, 10' 4" IH and 14' 6" door openings on the roster. However, there are 189 cars of virtually the same dimensions listed on sister line Louisiana & Arkansas as 36001-36200 except that they have a 9' door opening. Could these two groups be related?

Now series 20851-20900, 50' 6" Il, 10' 6" IH with 15' x 9' 10" door openings, should contain 50 cars but has only 14, plus 20859, 20866 and 20880 listed separately as XAP and covered under note S as above. That's just 17 cars. No other KCS cars match these dimensions. Hmmmm. Where are the other 33 cars? Also interesting, though not uncommon, series 20851 were originally XA and equipped with auto racks and chain tubes.

Yours Aye,


Garth Groff

I believe for my modeling needs either the Walthers Proto or the Proto 2000 kit will do just fine. We shall see which kit I stumble across first at the local swap meets. 

Again, thanks for all of the kind assistance.

Proto 2000 -- 30351 KCS #20855 kit 

Other car numbers probably in that vicinity -- 3034x or 3035x
