First Generation Steam Locomotives

“City of Truro” is a Great Western Railways City Class 4-4-0 Express Passenger Locomotive built in 1903. She held the world speed record of 102.3 mph for many years. Retired to the Great Western Museum in Swindon she was restored to mainline condition during 2004.   “611” is a Norfolk & Western Class J 4-8-4 Express Passenger Locomotive built in 1943. Capable of 15,000 miles per month they with the A’s and Yb’s of this exceptional Railroad continued to operate until 1960. 611 along with Class A 1218 are on display at the Virginia Museum of Transportation Roanoke.   British Rail’s Class 8 4-6-2 “Duke of Gloucester” was built in 1953 and features poppet valve gear of the British-Caprotti pattern. For a variety of reasons it was not a success BUT it has been rebuilt from the Barry wreck it was to the outstanding performer that it is today!

Advanced First Generation Steam Locomotives

This was the first locomotive project undertaken by Livio Dante Porta; 'Argentina' was a rebuild of a metre gauge locomotive, and remains one of the most efficient steam locomotives of all time. Currently the subject of a restoration appeal it is planned to initially secure the locomotive and then rebuild it!   André Chapelon’s 242 A1 4-8-4 was by all accounts a remarkable locomotive. With its 21 tons axle load this 3-cylinder compound was capable of developing 5,500hp. Sadly the locomotive was withdrawn in 1960 and broken up surely one of the greatest acts of folly in the history of the steam locomotive.   South African Railways Class 26 3450 4-8-4 is David Wardale’s rebuild of a 25 NC. Equipped with the Gas Producer Combustion System and Lempor Exhaust System it showed what coal fired steam locomotives could achieve given the opportunity.

Second Generation Steam Technology

Engine 52 8055 was built in 1942/1943 in Grafenstaden, in German occupied France. In 1996/7 52 8055 was rebuilt by Roger Waller and SLM using modern steam technology for EZF in Germany. Today 52 8055 is owned by DLM and is the most modern mainline steam locomotive in the world.   The paddle steamer Montreux has the first ship steam engine built in Switzerland since 1928. Remote controllable from the bridge it offers the same economics as diesel electric units and demonstrates the transferability of DLM’s modern steam technology.   The Brienz Rothorn Bahn in Switzerland has three of the DLM class H2/3 rack tank locomotives - numbers 12, 14 & 15. Number 12 was built in 1992 with 14 & 15 following in 1996. They are true second generation steam locomotives capable of competing environmentally and economically with diesel locomotives.
