Good (and not so lively) on the Berks & Hants

My col­league Doug Lan­dau is an ac­knowl­edged per­for­mance an­a­lyst, and I’m truly grate­ful to him for pulling to­gether de­tails of some out­stand­ing per­for­mances in re­cent years on the west­bound climb to Sav­er­nake. These are set out in Ta­ble 3, which in­cludes runs by Clan Line, Fly­ing Scots­man in its ‘Su­per A3’ guise with the 250lb boiler, and Duke of Glouces­ter, to which I have ap­pended col­umn 4 for my own re­cent run with Tor­nado. Doug Lan­dau has cal­cu­lated the horse­power out­puts over two sec­tions, both equiv­a­lent draw­bar horse­power and in­di­cated horse­power, from Mile­post 56 to Mile­post 70 and nearer the top of the bank from Mile­post 64 to 70. This has en­abled val­ues to be es­tab­lished for horse­power to ton and horse­power per square foot of grate, which make in­ter­est­ing read­ing. The gra­di­ents from New­bury to Sav­er­nake were de­scribed ear­lier. I should ex­plain the dis­crep­ancy of a few sec­onds be­tween the Sav­er­nake pass­ing time shown here and that in Ta­ble 2. Ta­ble 3 shows the time pass­ing Mile­post 70 it­self, whereas Sav­er­nake sta­tion site is 70.10 miles from Lon­don, and that pass­ing time ap­pears in Ta­ble 2. Ac­ton-based Driver Dave Davis (sadly de­ceased) fea­tured in sev­eral out­stand­ing per­for­mances over the Berks & Hants route with both Clan Line and Taw Val­ley in the late 1990s. Ta­ble 3 shows runs start­ing from New­bury Race­course, but there were oth­ers not shown here, which started from New­bury it­self.

Crack team

Thus, on Fe­bru­ary 15 1997, the re­doubtable team of Messrs Davis and Grey­stone pro­duced a per­for­mance with the smaller ‘West Coun­try’ Taw Val­ley. Its per­for­mance was only slightly in­fe­rior to that of Clan Line, av­er­ag­ing 66.1mph from Mile­post 64 to 70, with speed fall­ing from 67½mph at Bed­wyn to 64 at Sav­er­nake, and with a 13-coach train gross­ing 510 tons, against Clan Line’s 475 tons.
