Equipment.

Grand Trunk locomotives.

F. W. Morse, Superintendent of Motive Power, writes The Railway & Shipping World: "The G.T.R. system is now receiving from the Baldwin Locomotive Works 6 mogul locomotives & 4 10-wheelers, & a duplicate order from the Schenectady Locomotive Works. At present we are not building in Montréal, but may do so before the end of the year."

The 10-wheel passenger engines are illustrated on page 33. In designing these new classes of locomotives the intention has been to combine the best features of a number of recent designs; & the details have received unusual attention, both from Superintendent Morse & from the manufacturers, & such parts have been made especially substantial, while the passenger & freight locomotives are designed for particular classes of service, yet the parts which will require repairs & renewals are the same for both engines, which undoubtedly will reduce considerably the cost of maintenance. The passenger engines have a greater total weight than the freight engines of 14,500 lbs., but less weight on the drivers by 3,000 lbs.; the passenger engines also have larger driving wheels & a longer boiler, the latter resulting in a slightly greater heating surface for the 10-wheel locomotives. The diameter of the boiler & the dimensions of the fireboxes are the same for both classes.

The following is a list of the dimensions of both classes & of the special equipment of the engines built at the Baldwin Works:
