Thanks for sharing this, great find, particularly the DHR layout. I finally understand why people call the Darjeeling Himalayan Railway a "Toy train".
Wonder how the loco got all the way to the top without a crew, and in particular without the two sanders up front.
I think I recognized some actual locations from the prototype: Batasia Loop (top left), Pagla Jora (bridge in the middle, very small, may just be imagining this one).
Great little layout!
Reminds me of the fact that I still have plans for a DHR in 009.
