Two stages completed for the 35011 General Steam Navigation steam locomotive

0

The General Steam Navigation Locomotive Restoration Society (GSNLRS) has announced that it has made two important milestones in the restoration of its Southern Railways Merchant Marine Class No. 35011 “General Steam Navigation”.

Tractor trailer

Following discussions with various contractors, the GSNLRS accepted a quote from North Norfolk Railway Engineering for the restoration of the 35011 trailer truck.

Since the separation of the rear bogie from the rest of the main locomotive frame, the Company is preparing the rear bogie for the next stages of restoration. The volunteers did an incredible job of laying out and cleaning up, with North Norfolk Railway Engineering now taking over the rest of the work to restore the truck. GSN’s follower truck is of prefabricated construction, the only surviving example, which makes it quite unique.

The GSNLRS set up a fund called the Trailing Truck Transformers Fund Club to raise funds to cover the costs of restoring the tow truck. For more information or to donate to the fund, please click here.

Crank axle

One of the biggest challenges for the Company is to build a new crank axle for 35011, as the original was retired in 1966. Much research has been done to determine what grade of steel would be suitable for a new crank axle. crank. Together with Professor Karl Dearn from the University of Birmingham, they performed a finite element analysis and found suitable grade A4T steel for a crank axle. Work can now progress on the design work for the new crank axle.
