Mount Washington Cog Railway,
New Hampshire, USA

In October 2003 the world's first rack & pinion railway - The Mount Washington Cog Railway started work on redraughting their loco fleet, with the design work being carried out by Nigel in the UK.

During this time locomotive No.9 Waumbek became the first of the fleet to receive a Lempor exhaust and thus proved what Nigel had promised he could achieve - a very considerable decrease in fuel consumption brought about by much more complete combustion, leading to far less smoke and an increase in power. Very notably this installation was the first time a Lempor exhaust had been fitted to any locomotive in North America.

For an impartial summary of what has happened at Mount Washington read this report from Dave Lathrop. The report was originally hosted by RYPN.org. Following removal from their pages, and through their assistance, it is now available, in original form, on this site. By thanks to Dave Lathrop and Hume Kading for making this possible.

Since this initial work things have moved on apace with the (current) culmination of the work being the production of the world's first biodiesel fuelled steam railway locomotive.
