The photo above shows the original Cass 6 Boiler.  This boiler was replaced in 2004.  The steam for the cylinders is piped from the back of the steam chamber down the boiler sides.

The photo above shows the side of MRSRR 91 boiler.  The steam for the cylinders is piped from the steam chamber through the inside of the boiler to the smoke box where it enters a superheater. The output of the superheater is via pipes from the smoke box along the side of the boiler to the cylinders.  The pipe for the right cylinder is visible in the photo.
