I  can't really understand it, as they tend to be simple, robust designs and often,  as in this case, good-looking engines. The typically short tenders are big  enough to be useful coal, water and tool-carrying trucks yet not an encumberance  to driving.\u003c\/p\u003e    \u003cp align=\"left\"\u003eThis is a Derby 4F, Fowler's design for the Midland Railway.  Built to Don Young's design, it is a well-built engine. Silver soldered copper  boiler with superheaters, 80psi working pressure, feed by injector and axle pump  with auxiliary hand pump in the tender. Inside cylinders with slide valves  actuated by Joy valve gear.
