:
Gentlemen, In conversation with you some time since, I promised to send you the performance of the Class I engines on this division of the Pennsylvania Railroad ; in compliance with which promise, I inclose three statements showing the work of these engines from January i to July I, 1876. Two of these statements ("A" and " B") are copies from a letter from me to Mr. James Dredge, one " of the editors of London Engineering; the third, C," containing the same information regarding the Class I engines in use on the Susquehanna Division of the Northern Central Railway, from May I to
September
I, 1876. large amount of work done by these engines in a short time shows that they do not need the constant repairs which some people assert such engines would require, it being a commonly received
The
opinion that although Consolidation engines may haul more cars in a single train than lighter engines, These figures leave no ground for such fears. The they could not do so much work in a given time. engines are hauling trains on the same schedule as our ordinary lo-wheel engines work on, and you understand, of course, that owing to fluctuations in traffic we often have to run engines over our line empty, or with half trains, so that the average train is very much below the usual load. The maximum load on a level division, with which we expect the men to make time, may be taken at 90 cars, though
on one day we hauled
no
cars into Harrisburg.
Yours
respectfully,
HOWARD
FRY,
Superintendent of Motive Power.
