My LEGO version of the Baldwin DR-12-8-1500/2 "Centipede". The Centipede was Baldwin Locomotive Work's first attempt at a road diesel locomotive. Its unique feature was 12 axles which made the locomotive looked like a centipede. Unfortunately, it was not reliable and none was saved from the scrap yard. My MOC is powered by LEGO Power Functions. It follows LEGO 6 wide train toy style. It is approx. 60 studs long. Baldwin DR-12-8-1500/2 Centipede by dr_spock_888, on Flickr View from back. The Centipede was original built for passenger service but engine failures left it relegated to freight service. Access to Power Functions AAA battery box. The batteries also adds weight on top of the PF Train motor. Access to engineer in cab for playability (and changing Infrared Receiver channel): It can negiotiate LEGO R40 curves and switches. Although it looks like it is going to take out anything next to the curves. I had to add a lot of articulation to the wheel arrangement. It would look best on the largest ME curved track. I think it is a suitable MOC for all those metal axles I have been making for bogies. There is something interesting about having lots of wheels on equipment.

Built in 1952 by Pennsylvania Railroad, the "Queen Mary" was the world's largest freight car at the time. It was 121 feet long, weighed 250 tons and could carry 250 tons. Originally it was built as a depressed flatcar, class FD2. Later on in 1960 a "well" body was built for it to carry items which are narrow and tall like flywheel and rolling mill housings. The two bodies can be used interchangably on the same trucks depending which kind of load it is to carry. The Queen Mary was eventually retired in the 1990s during the Conrail era. The unit can be found today at the Altoona Railroaders Memorial Museum with the FD2 body. No one knows what became of the FW1 body. My MOC is the FW1 version of the Queen Mary flatcar. It follows LEGO 6 wide train style. It has 16 axles of standard LEGO bogies in groups of 4. It is 84 studs long. It can negiotiate LEGO R40 curves and switches.

New MOC! This is the first model of an electric locomotive I've built. The Pennsylvania Railroad used these odd-looking twin-unit electric locomotives starting in the 1910s. Each half of the locomotive was powered by a single large electric motor in the body, connected to the driving wheels via a jackshaft and side rods, resulting in an effective wheel arrangement of 4-4-0+0-4-4 (2'B+B2' in UIC notation). To me, the jackshaft-and-side-rods drive system is a key part of the DD1's appearance. Consequently, the first thing I did was to figure out how to replicate the mechanism as faithfully as possible within the width of the model. By SNOT-ing the sides of the locomotive, I was able to make the bodywork only 1 plate thick in places, allowing me to pass a technic half-beam behind them. As a side benefit, the studs on the side line up nicely with the rivet lines on the prototype. After figuring out the mechanicals, I designed the bodywork in LDD, then placed a whole bunch of BrickLink orders with Commander Wolf to acquire all the windows, 1x3 tiles, and the giant pile of brackets required for the SNOTwork. I actually finished the model a couple weeks ago, but the soggy weather and other commitments prevented me from taking photos until now. I also took some video: Brickshelf gallery Let me know what you think!

My PRR B1 has reproduced itself into a PRR Class BB1. When PRR bought the first batch of the units, they came in BB1 configuration. The units were semi-permanently joined together. Only later on in life did PRR separated them into single B1 units and ordered further units as B1. PRR Class BB1 by dr_spock_888, on Flickr As a BB1 model, there is room to add Power Functions. An XL-motor can replace the M-motor if more power is needed. I had to add tires to the drive wheels to give it more traction around curves. I find the 0-6-0 wheel configration fascinating in these electrics. YouTube video: More pics on my BrickShelf: http://www.brickshel...ry.cgi?f=539207

In 1917 Pennsylvania Railroad created the FF1 experimental electric locomotive. It was nicknamed Big Liz. PRR planned to electrify the Allegheny Mountains and have the FF1 haul freight through it. Big Liz was so strong that she would regularly ripped the couplers off the rolling stock of that era. Electrification didn't happen and Big Liz was scrapped in 1940. There was only one made and she was one of a kind. I followed LEGO 6 wide toy train designs and used Power Functions for motive power. The boxy boxcab design and 48 studs length provided ample room for AAA battery box, IR receiver, PF LED and M-motor. The prototype didn't go faster than 20.6 mph so I further geared down the M-motor output. PRR FF1 Big Liz by dr_spock_888, on Flickr The unique features of this locomotive are the jackshafts and side rods. I wanted to use 13L thin Technic liftarms for side rods. Since LEGO doesn't produce them in that size, I opted to make them with 123D Designer and Meshmixer. I sent the export file to my local public library for 3D printing. They came out to about 50 cents CAD each. The 3D printed pieces are useable but not LEGO plastic injection mold quality. It was challenging learning to use the software and DIY. I didn't yank out too much hair. Video of FF1 in action: Couple more pics on Brickshelf.

My little red caboose or cabin car in Pennsylvania Railroad terminology. Bobbers were simple wooden frame cabooses built in the 19th century. PRR made theirs with steel frames. That permitted their bobbers to be used in pushed service without being crushed. Their choice to use steel allowed their boobers to last well into the 20th century. PRR Bobber Caboose by dr_spock_888, on Flickr They were called bobbers because 2 axles gave a bobbing ride. I guess the modern ride equivalent would be of the U.K.'s Pacer railcars. Bobbers have a child's toyish feel to them. Maybe because many little children toy caboose designs are based off them.
