This 5” gauge Mallard shown under construction at Doncaster in 2018 is by Rod Ainsworth. He acquired it as a part-built Modelworks kit project. It had been completed up to running chassis by the previous owner.

Rod completely dismantled it to its component parts and re-assembled it with revised geometry for the Cartazzi axle and the bogie. The wheels were re-profiled and a new centre connecting rod and reversing gear were made from scratch. Body panels were also remade.

The LNER Pacific locomotives are probably the best known of all British steam locomotives today. Of those, pride of place must go to the A4 streamlined version, which holds the world speed record for a steam loco at 125.88mph, achieved by Mallard in July 1938.

The A4 class was designed by Sir Nigel Gresley in 1935, instantly recognizable with their streamlined casing. Thirty-five were built for passenger service on the East Coast Main Line out of Kings Cross, via York.

The original Gresley design was for a complete streamlined train called the Silver Jubilee to run between Kings Cross and Newcastle, in celebration of King George V’s quarter century on the throne. Those original trains were finished in silver-grey. A4s were finished in many colours during their lifetimes.

MIchael Breeze has produced a detailed design for A4 Sir Nigel Gresley in 5” gauge, along with many other classic locos from the LNER. Castings are available.
