4960 received a Lempor exhaust system on the GCR in the March 2005. It was found possible to re-use the old chimney (stack) and fit a liner to give the desired Lempor profile. In the photo to the left the new chimney liner can clearly be seen standing above the old chimney.

4960's original blast nozzle arrangement. This is a Kiesel Star as developed by the Pennsylvania Railroad and tested extensively at their world famous Altoona testing facilities. This version of the Kiesel Star appears to be the 1933 six lobe variety. March 13 2005. © Nigel Day

Note: Thanks to Sam Lanter and Shaun McMahon for filling me in on what type of nozzle this is.

4960 on test - note the manometer on the backhead. Note the safety equipment storage box labelled Fusees & Torpedos. Fusees are similar to the UK detonator whilst Torpedos are red flares lit to indicate any driver must stop. August 10 2005.  Nigel Day

In July 2006 Roger Hahn had the oppurtunity to visit the GCR and found 4960 in operation. He has kindly made available a video clip of the loco working hard upgrade with a heavy train. There is a diesel in the consist, also working hard, which is under the control of the steam locomotive driver (engineer in US speak).
