EXPLANATION OF TERMS.

The several cla.s.ses of locomotives manufactured by the Baldwin Locomotive Works have their respective distinguis.h.i.+ng names, which are derived and applied as follows:

All locomotives having one pair of driving-wheels are designated as B engines.

Those having two pairs of drivers, as C engines.

Those having three pairs of drivers, as D engines.

Those having four pairs of drivers, as E engines.

One or more figures united with one of these letters, B, C, D, or E, and preceding it, indicates the dimensions of cylinders, boiler, and other parts, and also the general plan of the locomotive: thus, 27-1/2 C designates the cla.s.s of eight-wheeled locomotives (ill.u.s.trated on pages 56 and 60) with two pairs of drivers and a four-wheeled truck, and with cylinders sixteen inches in diameter and twenty-two or twenty-four inches stroke. 34 E designates another cla.s.s (ill.u.s.trated on page 80), with four pairs of drivers and a pony truck, and with cylinders twenty inches in diameter and twenty-four inches stroke.

In like manner all the other cla.s.ses are designated by a combination of certain letters and figures.

All corresponding important parts of locomotives of the same cla.s.s are made interchangeable and exact duplicates.

The following table gives a summary of the princ.i.p.al cla.s.ses of locomotives of our manufacture:

PREFATORY.

The dimensions given in the following Catalogue are for locomotives of four feet eight and a half inches gauge, unless otherwise stated.

The _loads_ given under each cla.s.s are invariably in gross tons of twenty-two hundred and forty pounds, and include both cars and lading.

All the locomotives described in this Catalogue are sold with the guarantee that they will haul, on a straight track in good condition, the loads stated. Their actual performance under favorable circ.u.mstances may be relied upon largely to exceed the figures given in the guarantee.

The feed-water for all locomotives specified is supplied by two pumps, or one pump and one injector. One or more injectors can also be supplied in addition to the two pumps, if desired.
