Locomotive Specifications

8783 'Phoenix' will be built to the D16/2 original 'super Claud' specification, with additional modifications and upgrades. Such as improved lubrication and improving maintenance. We intend to fit the locomotive as per the royal LNER specifications, with the brass funnel and increased level of brass work.

D16/2 had a total working weight of 94-3-0 tons, max working pressure of 180lbs per square inch and a tractive effort of 4.76.

The group plans to make some changes to the D16/2 design by incorporating some ideas and improvements made to other engines. Some ideas have been listed below.


Like all engines curtain areas need to be cleaned out after use, the smoke box and ash pan being the main areas. The engines suffered with ash falling and getting onto the motion and important moving parts. Information supplied to us by an Ex British rail fitter. We will be undertaking improvements to how the engines are cleaned out and stopping the ash from falling through. Inspection lights in key areas will be installed for maintenance during night time preparations or early morning preparations.


Temperature gauges will be added near and on working parts, which will supply the crew continuous updates of the temperature. This will look to eliminate any future serious damage coursed by poor lubrication. Also increasing the size of oil pots and number of pipes to those oiling points, improving the length of time running and stopping any blocked pipes.


We will also look to make duplicate parts for important motion components and well used parts, lowering the down time of the engine between overhauls or during serious maintenance.
