The SD80MAC and SD90MAC are no longer shown (just the SD70M-2 and SD70ACe) but the first passenger locomotive shown is the Long Island Rail Road's DM/DE30AC!
Electro-Motive Corporation was an early builder of gas-electric railcars, later adding locomotives; in fact, I'm not quite sure why I'm not as interested in gas boxcabs as in oil/diesel-electric boxcabs. Nevertheless, EMC was founded in 1922 by H. C. Hamilton, President, who had been in the heavy autotruck business, and Paul Turner; Hamilton brought in such heavy talent as C. F. ("Boss") Kettering (later to head GM) and Richard Dilworth (GM's Chief engineer from 1934). Kettering and his son, Eugene W. Kettering, designed the GM 567 engine that really made the diesel-electric locomotive what it is today and Dilworth put it in the early main-line and switching engines.
General Motors Corporation got the diesel bug in 1929 and bought Winton Engine Co., which made most of EMC's engines, the following year. Later that year (1930), GM also bought out EMC, changing it's name to Electro-Motive Division.
EMC's early, and very interesting, boxcabs are rather heavily covered on my various ALCo-GE-IR boxcab pages, q.v., and especially on my Other Boxcabs page.



Then EMC built nine boxy-cab units for SF and CB&Q in 1935-36 (see Pinkepank/Marre) and two 1,000hp E6 boxcabs (yes, Virginia, E6 boxcabs!) - see my Other Boxcabs page.
I finally found the photos I took of LIRR Power Pack #622 (a Nov 1950 F7a, s/n 12626, heavily modified for HEP service on push-pulls) up at Danbury, Connecticut (of all places), when the NRHS/LIST fan trip stopped there in late 1990; I happened to be in the front vestibule on the return trip and noticed that the dual headlight housing had a most interesting "Chinese" or "hieroglyphic" emblem on each side of the front face of the casting:

These are details of details of details! The resolution of the original photo was good but the third generation enlargement suffers greatly from pixellation; nevertheless you should be able to make out the characters in the third shot (enlarged, cropped and turned 90° counter-clockwise) as EM C, even though the "E" is very dimly delineated.
An EMC casting on a 1950 EMD loco? ¡Muy loco!
See "Diesel Locomotives: The First 50 Years - A Guide to Diesels Built Before 1972, by Louis A. Marre, Railroad Reference Series No. 10, Kalmbach Publishing Corp., 1995, ISBN 0-89024-258-5, for great coverage of early EMC/EMD locos; this and other references may be found on my Boxcabs Bibliography.
Anent EMC and the B&O Museum, while there photographing boxcab loco CNJ #1000, the first commercial oil (diesel)-electric, I spotted the nose of early (the very first) 1937 EMC EA, B&O #51, inside the shop undergoing restoration and was able to take these poor pix through the door:

That EA, the first of six, #51-56, led to the immensely-popular E3, E6, E7, E8, and E9
series.
I owed you folks a page on my wide-cab, cowl-bodied EMD models and fantasies
thereupon. You had my permission to nag me about them.
Among the many items were to be the (tall) stories (with pictures as soon as I could get my scanner running again or my digital camera cranking) of the:
See my Model Railroading pages for some of this; you can get a peek at them on my BW (HO) Saga.
Rather than hold you up, I have decided to publish the text of an incomplete article (with only partial illustrations) of the story of the BIG BOY II - THE LEGENDARY DDP45:

See below for modeling info.
It occurs to me, what with all the wonders of the Berlinerwerke over which there has been so much written, that there has never been an article about the first special BW rail vehicle ever publicly shown (there IS one earlier one, a veritable chef d'oeuvre, un veritable pièce de résistance, yet unfinished, that only the late, great Ira Rothberg was ever privileged to see and, as far as I know, he won't tell).
First conceived on 20 January 1974, detailed on 21 January 1974, and drawn on 22 January of that year, the DDP45 was actually started on 15 November and final assembly occurred on 04 April 1975. After a shakedown run around the Berlinerwerke system, the prime coat was applied on 05 April. One assumes, from the incomplete records of that latter date, a Saturday, and the propensity of the owner of the Berlinerwerke to such last-minute feats, that a meet of the Sunrise Trail Division of the Northeast Region of the National Model Railroad Association occurred on 05 April 1975 at which the engine was first shown.
The idea sprang from the success of the original Union Pacific/Alco (American Locomotive Company) Challenger 4-6-6-4 and Big Boy 4-8-8-4 locomotives in the 1940's, followed by the series of oil and coal turbine engines in the 50's. Giant power always fascinated the UP management and they went at it one last time in 1963 with a competition for a series of double-engined diesel behemoths from ALCo, General Electric, and the Electro-Motive Division of General Motors. GE's contribution was the U50, basically a pair of 2,500HP FDL-16-engined U25s on a single chassis riding on four four-wheel trucks with two pairs each under span bolsters (all recycled from GE gas turbines). Some 15+ U50 units, both cab and booster units, were built in UP's 31-series. In 1964, Alco chimed in with two huge C-855s and a C-855B, also on paired four-wheel trucks and powered by two 2,750HP 251C engines. Only the one A-B-A set, UP 60-60B-61, was built. EMD, however, responded more positively to the challenge with the gigantic 1964 DD35, a cabless double GP-35 booster powered by two 2,500HP 567D3A diesels. Most unique of all were the enormous D-D (four-axle) trucks. In 1965, EMD broke with its announced intention and came out with the cab version, the DD35A. Over 28 booster units and 15 cab models were built, SP's 8400 - 8402 and UP's 72B - 94B and the 71-series. In 1966, EMD catalogued, but never built, a 645-engined DD-40 cab unit.
Later, timed to coincide with the centennial of the driving of the Golden Spike at Promontory, Utah, in 1969, EMD produced the last of the breed, the fantastic DDA40X "Centennial" locomotives, with two 3,300HP 645 engines, a full-width cowl-type cab, and the prototype of the Dash 2 modular electronic control system. These monsters rode on updated D (four-axle) trucks, separated by a staggering 8,280 gallon fuel tank. Not to be left out, GE brought out a less spectacular (and less successful) six-axle (C-C) version of its U50 in, the U50C, of which some 40 were built from 1969 to 1971 in UP's 5000-series. 47 EMD DDA40X units were built as UP 6900 and up. The 6900 is preserved in running condition with the venerable 4-8-4 Northern 844 and 4-6-6-4 Challenger 3985 at UP's Cheyenne roundhouse (and the 6946, built 9-1971, b/n 35520, last of 47 "Centennial" locomotives constructed, was donated by UP to the Feather River Rail Society and sits at their Portola Railroad Museum in the high Sierras).
About this time, the UP was giving up on giant power as not sufficiently cost-effective. Some stalwarts in the Motive Power Department, however, asked EMD to consider a double version of the 3,600HP 645F-engined SD45. EMD declined, stating low profits forecast for another special design, and referred the UP team to the Berlinerwerke, with which EMD had a close working relationship. Using a maximum of standard EMD components, the BW staff quickly came up with specifications for the biggest, most powerful single-chassis locomotive of all time. Instantly dubbed the "Big Boy II", the DDP45 design was soon completed and a prototype begun as noted above at the beginning of this article. To get some idea of the relative size of these giants, let's compare a few of them:
O'all Wheel Cooper's
Length base Weight Loading
Big Boy 4-8-8-4 85' 3½"* 47' 3"* 772,000
DD35 88' 2" 55' E-90
DDA40X 98' 5" 65' 65' 545,432 E-90
DDP45 117' 83' 10" E-90
* - Big Boy length without tender (130' 9½" overall), driver wheelbase
(72' 5½" total engine wheelbase and 117' 6 " overall wheelbase).
{additional data to follow}
The DDP45 uses two standard EMD D trucks with heavier journals, spanning two pairs of DD35 fuel tanks (it was felt that it was safer and less expensive to have multiple smaller tanks). A major difference was that the body has a full cowl; the body is made from (front-to-rear) a standard F45 cab and cowl, a reversed FP45 cowl, and an FP45 rear with steam generator.
Speaking of engineering, it might be of interest to compare the technical specifications of these units with some of the newest power available today. Morrison- Knudsen, a well-respected rebuilder, went all-out in 1994 and put out an all-new single-engine locomotive, the MK5000C, rated at a whopping 5,000-hp! Both GE and EMD jumped on the bandwagon with an entirely new generation of 6,000-hp single-engine locomotives which purport to have solved problems of power, steering, tracking, and adhesion. Specifications (as available) for some of these follow:

The first is the chassis without the body, showing the brass channel I used to join the front 2/3 and the back 2/3 of two Athearn so-called DD40s and the Plastruct "prototypical" side reinforcing frames I crafted. I even took a close-up to show how I milled the frames to accept the two outboard flywheels, as well as the spacing of the two sets of fuel tanks (fuhgeddaboudit!):

Here is the inside of the chassis, showing the machine screws which I ran up through the extra motor mount holes, the heads of others I ran down through the channel into threaded holes in the tanks, and the extent of the chassis milling:

Next, I'll show you the underside of the chassis, so you can see the screw heads deep up inside the motor mount holes and the threaded holes through the fuel tanks:

OK, now let's turn to the underside of the body to see how that was built of an F45 front, a reversed FP45 center, and an FP45 rear:

[These photos were appallingly dark but a bit of image processing on 20 Jan 01 brought out the latent details.]

Now, if you like that (the DDP45), you should see Jeff Mott's
EMD TD60.

Karen Parker, RR historienne sans égale, was poking around in the Berlinerwerke files again and turned up a photo of UP/BW DDDDP45 #7100; here, with some very minor, but able, assistance from the BW Art Dept., it is, in all its glory:


Karen is indefatigable; she dug further into the BW files under SF and found (with a little help) these photos of the AT&SF warbonnetted F-55 and FP-55:
