Looks a lot like the Pennsylvania T1. The T1 was one of the sharpest looking US steamers, but with four cylinders on only eight axles she slipped too much to be called truly successful.

My personal favorite is the Norfolk and Western J.

Equally at home pulling a long varnish up the side of a mountain or blasting across the open plains. The 611 is still runnable, but the lawyers have it tied up in a roundhouse. Can't get the insurance to run it.

There's a reason for that. SA Railways copied the streamlining of the T1, which appeared a year earlier. But the 520 mechanicals were based on the more conventional 4-8-4 500B "Mountain" series which ran the interstate line, the 520 being a reduced weight version capable of running on the 60lb local tracks.

That's the Adelaide-Melbourne run - 2.2% climb out of the city then 500 miles of open plains

If you are ever in Skagway, try out the White Pass Line.
