Norfolk and Western 1218
Norfolk & Western 1218 is a steam locomotive that at one time was the strongest-pulling operational steam locomotive in the world. It is a four-cylinder simple articulated locomotive with a 2-6-6-4 (Whyte system) wheel arrangement. The Norfolk & Western Railway built it in 1943 at its Roanoke Shops in Roanoke, Virginia, and was part of the Norfolk & Western's class A fleet of fast freight locomotives. It was retired from regular revenue service in 1959, but Norfolk & Western successor Norfolk Southern Railway operated it in excursion service from 1987 to 1991. Today it is on display at the Virginia Museum of Transportation in Roanoke.

NOTE: Make sure that the model CV155=1 project is running "Articulated" sounds with both front and rear cylinders.
Low speed: A standing Locomotive collects condensed water in its cylinder as trapped steam cools. Since it isn't
Compressible, this water can blow out a cylinder head when the engine starts.
To avoid this ,the engineer first opens valves called cylinder cocks under each end of the
cylinders(sometimes in the middle too ). Then when the engine starts,the exhaust steam comes
Whoooshing out of the cylinder cocks with the condensate instead of chugging up the stack.
Engines doing this spray steam from under their cylinder.
The starting steam cock open is controlled by CV147 (about =14) since steam loco has no drier.
