$4,600, according to The Train Department.
I guessed Roundhouse went R/C only because it's a lot easier to put a reversing servo in each chassis than build a mechanical linkage which accommodates the articulation.
It's an appealing model, and huge - over a half meter long.

It is nearly two locomotives. 
Two full engines. While there is only one boiler, burner, and fuel assembly, there are several components not found on a conventional Roundhouse model: two hinge points in the chassis and flexible steam delivery lines plus one return line. This model also seems to have more detail than is average for Roundhouse.
I'm thinking about ordering one. My coal project is taking awhile, and I don't want to rush that.

It appears from those photos the prototype used a drive shaft with universal joints and telescoping sections to control the weigh shafts and lifting arms on each engine - probably the component Roundhouse found too costly to offer in manual control. It looks similar to a Shay's driveshaft.
