Re-echo

I remember the sudden drop in the note of the station bell, as we roar through, perhaps with 16 coaches; sweep up to milepost 9½, and then, with increasing thunder from the exhaust, fairly rush the fells at Milnthorpe at the foot of the climb to Grayrigg, until the steady thunderous beat re-echoes past Mosedale Hall, still at 40 m.p.h.
