Should have remembered this group--the 40 T-3 4-8-2s, homebuilt by Mt. Claire using rebuilt boilers from older 4-6-2s and 2-8-2 in P-1aa and various Q-1 classes between 1942 and 1948; No. 5594 would be the last steam locomotive built at Mt. Claire.  As near as I can figure, these engines ran mostly west of Cumberland on the Chicago line in passenger service to Pittsburgh and in fast freight service in Ohio.  Oh, these engines have 70-inch drivers and long-frame Baker valve gear--same as Bachmann's USRA light and heavy 4-8-2s.

The first T-3 on an excursion in Ohio in 1955:

In the late 1950s, the growing diesel roster was about to outgrow the two- and three-digit number series it was assigned to, and the steam roster was continuing to shrink, so the road went into a general renumbering scheme in which all steamers  were renumbered into a three digit series and the diesels got 4-digit numbers.  That is why the former No. 5562 now wears No. 704 in this photo at Butler, Pa.:

http://www.rr-fallenflags.org/bo/bo-s704r.jpg

This photo brings sadness to me as not only is the engine out of service and awaiting scrapping--but it was photographed in 1961, well after the end of steam operations, well after the establishment of the museum in Baltimore.  The railroad that preserved so much also let way too much of its later steam glory slip away.

Glad you love it all.

That lump is a stone shield for front frame mounted air compressors, a common location for pumps on later engines (or rebuilt ones, as in a P-7c or P-7d, or a Reading T-1 4-8-4) that also had cast frames.  The shields B&O used on the rebuilt P-7s were their own.  Baldwin used a semi-cylindrical shape with a half-domed top (see B&O's EM-1 2-8-8-4, or a number of Baldwin designed 4-8-4s, including those of the Atlantic Coast Line, Richmond, Fredericksburg & Potomac, and the Santa Fe, the latter represented by a Bachmann model).  Lima used a pair of angular-looking shields (see NKP 2-8-4s), while Alco used a flat shield with two little angled tops (UP 4-8-4s, 4-6-6-4s, and 4-8-8-4s).  Of course, there would be exceptions, usually in the case of engines that were ordered as copies of locomotives orignially designed by someone else (L&N 2-8-4s built by Lima in 1949 that were copies of engines originally designed and built by Baldwin in the early 1940s).

Next reading assignment--Model Railroader's Locomotive Cyclopedia, Vol. 1, Steam Locomotives (a B&O Big 6 is in there, if I remember correctly), or check out Hundmann Publications' Locomotive Cyclopedia, Vols. 1 and 2 (which includes EM-1 2-8-8-4s, and a B&A 4-6-6T).  And while I haven't had the chance to study the Hundmann books properly, it is likely that, like the MR book, that it has a section on locomotive appliances (air compressors, injectors, feedwater heaters, stokers, etc.), that also shows proper practice in regard to piping this stuff up for those extreme detail hounds.

For me as a former engineering student who had unfortunate problems with calculus, this stuff is fascinating.

A site with a few photos that help illustrate these shields:

NKP 2-8-2 , built by Lima, based on the USRA light 2-8-2; note that this engine has long-frame Baker valve gear (also used by NYC 4-6-4, C&O 2-6-6-6s, and B&O Big Sixes):

The photo further down of the Illinois Central 4-8-2 doesn't enlarge (blast!), but the engine does illustrate that the IC didn't bother with stone shields!

I need to get busy on my own layout!

Both of you could be right.  This is just something I had heard about, including that this was supposedly the reason CV got out of the truck business.  Wonder what the real story might be?

I'm not a teacher, at least not as part of a school system.  I am an auditor with the state of West Virginia (I make sure businessmen report wages and pay unemployment tax properly), and I guess I am a teacher in that I spend a lot of my time explaining unemployment compensation law and related matters to these employers so they can pay the appropriate taxes properly.  This includes making sure they do not pay too much tax as much as making sure they pay what they owe.  After all, they can use the money for their business to help make more jobs!

Funny that you talk about "homework;" that gave me the idea that you can use a reading list.  Here are some things I think you'll like (even if your wallet doesn't).  I am recalling some of the titles by memory (my library is downstairs) so not all of them may be totally accurate, but you have a good and intelligent readership on this thread, they can correct me and make additional suggestions:

B&O Power, by Larry Sagle and Al Staufer, published by Al Staufer, 1964, no longer in print.  B&O locomotives from 1827 to 1960, written mostly by B&O's publicity man of the time.

A Centenial History of the Baltimore & Ohio Railroad, by Edward Hungerford (2 volumes), published in 1927 as part of the B&O's centenial.  History of the road up to that time, although something of a PR piece (B&O historian Herb Harwood called it an "opera liberato, or something like that).

http://www.watertowndailytimes.com/article/20090705/COL03/307059997/-1/COL03

Impossible Challenge, by Herb H. Harwood; currently available from Barhard Roberts and Company; history of the B&O's original lines in Maryland from Baltimore to Harpers Ferry.

East End, the Neck of the Bottle, Jeffrey Hollis and Charles Roberts, Barnhard Roberts and Company; B&O from Harpers Ferry to Cumberland.

West End, by Charles Roberts, Barnhard Roberts and Company; B&O from Cumberland to Grafton.

Royal Blue Line, Herb H. Harwood, Barnhard Roberts and Company, B&O from Baltimore to Jersey City (New York City).

Sand Patch, Charles Roberts, Barnhard Roberts and Company; B&O from Cumberland to Connelsville, Pa.

While looking up the Barnhard Roberts material, I came across this:

Be careful not to have too much fun, for your wallet's sake!

Again, I must thank you for your kind words.

I don't know if you've seen this thread, but if you haven't, here are some other old-style things for reference and in some cases to keep your old engines company.

After all, model railroaders do not live by locomotives alone!

Johnson Bar Jeff likes 19th century power; he might like these links (and consider this locomotive another to wish for):

Although this is an HO forum, Johnson Bar may want to consider a change to O scale, simply because of what is available (even though it's not cheap).

P. D. Lethbridge found some interesting Mallet photos.  The first one of the 2-8-8-0 with a short tender is a builder's photo; this is about how all would have looked as delivered, in compound configuration and short tenders.  The three-truck tender job he found is notable not only for the clear view of the tank (and I have one in my original post as well), but for the location--that's Grafton, W.Va., which had a track layout, some structures with unusual features, and a town above on a mountainside that looked like something John Allen might have cooked up.

Among these features: a junction layout at the west end of the yard that included a double track split alongside the roundhouse, and a branch junction that headed south (eventually to Charleston, W.Va) that was a wye configuration that overlapped the mainline junction and also enclosed the roundhouse; the same roundhouse was also part of a pedestrian bridge that went over this junction, and that included a walkway that curved along its roof from one side of the house to the other; a large stone shop building that dated to the 1850s; a station from 1910 next to a railroad hotel built in the 1880s (the hotel is visible in the background of the three-truck tender photo); all of this was just across the tracks or within sight of the station, including interlocking towers that were active until recent years.  Going further back, there was once an earlier roundhouse in Grafton that was like the roundhouse that is being restored in Martinsburg, W.Va. (this had been a B&O standard design used in several locations, including twin roundhouses at Piemont; they were actually a form of building kit, with cast iron girders made at Mt. Claire).  I'll try to find some photos later.

I would be modeling the B&O myself if I weren't so big into C&O's modern steam.  And wasn't it Charles Roberts who said every railfan had two favorite railroads, the B&O and another one?

Until someone decides B&O power is worth making, there is this somewhat pricey alternative--but even then, he's cheaper than most brass engines. . .

http://eddystonelocomotives.com/

This hobby shop in Laurel, Md. also handles brass engines, some of which are not that expensive;the firm is also a major distributor for Bachmann:

http://www.peachcreekshops.com/

Hope this helps.

Just for fun, had to include this video link; the tape this is from (and I own a copy) has original live sound, and a big chunk of the tape is on my C&O, including several Alleghenies.

http://www.youtube.com/watch?v=rI99Dvpxo2w&NR=1

Have fun.

Ah yes, the Chicago Terminal 2-6-0's--more like a very fat 0-6-0, with the main rod going to the rear driver.  A special engine for switching and transfer work.

Chicago Terminal actually ended B&O steam operations some time after B&O proper did, with 0-8-0s that also handled passenger trains from the station in Chicago to the service yard there.  I seem to recall the date may have been as late as 1960.  Can anyone confirm this?

While we have been having fun with a little old Varney Dockside, the prototype was actually a special-purpose engine used in only one city in its original form.  At the same time, the Baltimore & Ohio is a popular prototype, and was once one of the 4 or 5 most notable railroads in the country (and was, with the Reading, the Pennsylvania, and an unnamed Short Line, one of the four roads on the Monopoly game board).

There have been models available of some B&O inspired protoypes, but most either were freelanced to a certain extent for mass market purposes (Mantua/Tyco's 4-6-2 is based on the P-7c), or were later known for mechanism problems and/or ancient tooling (Rivarossi's S-1 2-10-2, Athearn's USRA 2-8-2 and 4-6-2).  This suggests the question--what would be some appropriate engines for somebody to make that might sell well enough to justify the tooling costs?  These are my ideas--what would be yours?

2-8-2--Q-3 and Q-4, both with either 63 or 64 inch drivers and similar general overall proportions.  The Q-3 is the USRA light 2-8-2, of which B&O had 100, including the first one, No. 4500, now in the B&O Museum at Baltimore.  The Q-4 looked considerably different, but was essentially similar, the differences largely being a B&O cab, somewhat different domes, a B&O version of a Vanderbilt tank, and Baker valve gear.

http://www.northeast.railfan.net/images/bo4437sa.jpg

4-6-2--Three principle classes come to mind--P-5 (USRA original), P-6 (B&O modified copy, with many of the same detail changes exhibited by the Q-4), and the famous P-7 President series (apparently inspired by the Pennsy's K4s).  The principle differences between the P-7 and the K-4 were a radial stay (conventional) firebox and 250 vs. 205 psi boiler pressure.  Even the valve gear looked the same.

A steamlined variant in action, and also the now-preserved 5300:

http://www.youtube.com/watch?v=TbCFdocYkiA

The B&O was also a big user of 2-10-2s, called Big Sixes because they were big and because they were numbered in the 6000 series.  Most numerous and best of these were the S-1s and S-1as.  These engines had 64-inch drivers and Baker valve gear, suggesting a USRA heavy 2-10-2 mechanism could be a good starting point:

http://photoswest.org/cgi-bin/imager?00002525

http://www.northeast.railfan.net/images/bo6179s.jpg

2-8-8-0--70 engines, in classes EL-1, 2, 3, and 5, very much the standard B&O heavy articulated.  If someone were to be modeling Rowlesburg's helper station in the glory days, he would need at least a dozen of these beasts (and this is the reason I would nominate this one-road engine).  The photos below represent most of the engnes, most of which were converted to simple operation in the 1920s from their original compound configuration:

http://www.rr-fallenflags.org/bo/bo-s7127.jpg

Both front and rear engines of this EL-5 have Baker gear, but the valve gear frames are different:

http://www.northeast.railfan.net/images/bo7151sa.jpg

Walscharts gear on both engines, but check out the three-truck tender!  That is one item I would not expect anybody to offer.

Assigned to helper service at Martinsburg, W.Va.; check out the roundhouse and shop buildings from 1866 that are still there!

http://www.northeast.railfan.net/images/bo7141s.jpg

This is one that stayed a compound (note different cylinder sizes between front and rear engines); also notice that the engine has two types of valve gear, Walscharts on the rear engine, and Baker on the front engine:

http://www.northeast.railfan.net/images/bo7123s.jpg

Finally, simply because it's a favorite and a modern steam classic, the EM-1 2-8-8-4, with 64-inch drivers (same as a reversed engine of the same wheel arrangement, a Southern Pacific 4-8-8-2 Cab Forward):

The VC-12 is a different tank, of C&O design; the original short or medium tank was based on a Harriman (UP, SP) version.

One of the most fascinating things about steam railroading was all the custom designed equipment, structures, and other things, some even as small as machinist's hammers.

Jonathan and Woody,

Glad you like what you see, and hope you are using this as a springboard to look for other photos and things.  And I'm glad Woody spotted that bucket--that's something I missed.

One of the interesting things about these 0-4-0Ts is how compact they were, with the air compressor and the power reverse being in a recess in the cab or in the cab itself.  At the same time, it is fascinating that the B&O put so much "state of the art" technology into these 4 engines in a very secondary service--power reverse, piston valves and Walschart's valve gear, and superheating.

Chain shouldn't be too hard to find, based on this page from Walthers, just using the the word "chain,"  There are some other items in there, like chain link fence, but there is chain, too:

http://www.walthers.com/exec/search?category=&scale=H&manu=&item=&keywords=chain&words=restrict&instock=Q&split=30&Submit=Search

Now, what to use for hooks?  Would these be small enough, or would something scratched up from a piece of wire be better?
