Murdoch17 posted a topic in LEGO Train TechThis blue train is marked (2-6-0+0-6-2 Garratt, for heavy duty rotary snow plow jobs) number 4, and joins the family of similar mid-1880's engines such as (4-2-4, for military transport) green 1, (4-4-0, for freight) yellow 2, and (4-6-0, for passengers) red 3. The Garratt-type steam locomotive is perfect for use on the mountainous terrain of Colorado Rocky Mountains, with it's double steam locomotive pistons sets. (Before anyone says anything about Garratt loco's not being ever sold into the North American market, I'll say it's an experimental prototype to help with a motive power shortage. It may have been seen by the owner as a economical way of sending one locomotive to do the job of two.) This steam powered rotary snowplow was inspired by the real-world Denver and Rio Grande's narrow gauge plow "OY", as now seen on the Cumbres and Toltec RR in New Mexico / Colorado. I've decided to name my plow "YO" in tribute to my inspiration, using this part from the original Toy Story sets on the tender as the marker. The roof of the front of the plow comes off to reveal the cab for the plow operator. (Yes, the front "blade" does spin around.) The rear of the plow features the coal tender with a ladder from the water tank-top down to the magnetic coupler. This engine was originally a SRW locomotive works product, (made by Anthony Sava and formerly available on Bricklink until LEGO sadly removed most of his models) I reworked the engine to have working pistons and side-rods plus a longer frame. This made it from 2-4-0+0-4-2 to a 2-6-0+0-6-2, among other smaller updates to the engine. The rear of the steam locomotive. This part in black goes on the cab walls (it's the number 4) A simple caboose, for the snow plow train. I used a pair interesting windscreen parts for the cupola windows. NOTES: The Garratt is already 100% finished, some of the parts for the plow and caboose are already found... doing a major reorganization of the parts supply, and am amazed at what I'm finding already!
This model is the last of the original Museum of Transportation vehicles I have planned on buying, but that doesn't mean I won't have more in the future... who knows what may happen. This model will be built at some point in 2019. Real World Background: Here is Union Pacific rotary snowplow 900081. It was designed and built in 1966 at the UP Omaha shops, and is the heaviest rotary snowplow ever built, weighing 367,400 lbs. Three or four diesel locomotives, which were controlled from the non-propelled plow, pushed it at four to six mph. The snowplow is powered by an EMD 16 cylinder 3,000hp turbocharged diesel engine that drives an electric generator, which provides power to turn the 12’ rotary blades at up to 150 rpm. A steam generator provided heat to the cab and can thaw out the blades if they became frozen. This rotary snowplow was last used in Green River, WY in the mid 1980’s, and it was donated to the Museum of Transportation in St. Louis, Missouri in 1994 by the Union Pacific, where it is still seen today. LEGO model notes: I was inspired by Dr_Spock_888 and his rotary snowplow to build my own way back in 2014. Needless to say, it the originally 8 wide model didn't come out quite right at that time, so I put it aside for quite some time. I just recently remade the model into a 6 wide body with a 10 wide blade section, and have have smoothed out the roof studs with tiles. As before, the words "UP" (the initials of the former owner Union Pacific) should go on the studs towards the middle, while "900081" should go on the studs in the center in printed 1 x 1 tiles, right below the two UP tiles. The blades are actually part of Dr_Spock_888's design, but mine do not move with the train like his... mine are not connected to the wheels on the track, and do not move unless you spin them with your hand.
