I got a few images of some nice trains and thought I would share.
BNSF under a great sky,
This was a scale engine meet where the trains run on 7 1/2 inch track. But they do haul passengers so I figure they count as transportation.
The first train and this one have gasoline engines in them that drive hydraulic motors on each axle. They are absolutely beautiful and the detail is amazing.
Some were coal burning steam engines like this one.
And some used propane to fire the boiler on their steam engine.
Then there was the bare bones, basic coal burner. But hey, it had enough power to pull the engineer and the cooler. What else do you need?
