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 class 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 circumstances 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.
