Not a snow plow, but a weed plow!
Have you ever shown this intriguing steam railcar?
I was too disorganized to actually do a build thread for it unfortunately. It was a bit of a learning curve for me so it had a very long construction period. I think I first posted about it in
this post here in december 2020, but the construction actually started way back in 2019. After ironing out the bugs it has been a reliable and useful member of the rollingstock fleet though, and the preferred rollingstock to take when visiting other lines away from the wires. Here's some pictures from the construction phase!
Precision accurate concept drawings
The finished bogies in undercoat. Thanks Jake for drawing and printing the roller bearing axle boxes, the first application of 3D printing to any rollingstock in the fleet. A lot of attention was paid to making sure this very long and heavy car would run well on my bad track, the axles can twist relative to each other and there's plenty of travel in the secondary suspension springs.

The boiler, water tank and engine unit mounted to the frame, work starts on fitting up the plumbing. The plumbing went through a number of revisions so the final layout ended up quite different from what is shown here.

It finally steamed for the first time in late 2019, though testing and commissioning would still take nearly two more years. We got there in the end though, it has since been a reliable unit clocking up the kilometers here and on other lines it has visited.
