The 4-8-2 Mountain steam locomotive (known as a Mohawk on the New York Central) was one of the more powerful of the mid-period steam engines.  It is the direct ancestor of the 4-8-4 Northern steamer, which gained an added trailing axle when the new "superpower" design enlarged the firebox (much as the Mikado evolved into the Berkshire).  Shown above is one from the Illinois Central (IC); shown below is one of the enormous M-1 Mountain locomotives of the Pennsylvania RR (PRR), now preserved at the Railroad Museum of PA.

In April of 2003, MTH released their Premier line model of the PRR M1b Mountain. It is an exquisite piece of modelmaking that looks great and runs incredibly well.  Here are some photographs showing the details of this model.  The first is an overall shot of the locomotive.

The second is an overall shot of the tender. Yes, it's THAT enormous!

The next shows the detail of the "face" of the locomotive. Note the scale coupler.

Presto! The scale coupler drops away into the pilot as the prototype did!

Here's detail of the sand dome and the various lines coming out.

Further down, here's detail of the valve gear, rods, and drivers.

Detail at the top of the boiler and firebox.

The cab, with sliding windows and a very nice engineer figure.

The top of the tender deck. Note the six hatches.

The hatches open to reveal the volume control, charging jack, and smoke switch.

Finally, the doghouse, equipped with its own figure.
