gnated muslin laid
on the ties. The ends of the rails were not japanned, but were
electroplated, to give good contact surfaces for fish-plates and copper
bonds."
The following notes of Mr. Frederick A. Scheffler, who designed the
passenger locomotive for the 1882 road, throw an interesting light on
its technical details:
"In May, 1881, I was engaged by Mr. M. F. Moore, who was the first
General Manager of the Edison Company for Isolated Lighting, as a
draftsman to undertake the work of designing and building Edison's
electric locomotive No. 2.
"Previous to that time I had been employed in the engineering department
of Grant Locomotive Works, Paterson, New Jersey, and the Rhode Island
Locomotive Works, Providence, Rhode Island....
"It was Mr. Edison's idea, as I understood it at that time, to build a
locomotive along the general lines of steam locomotives (at least,
in outward appearance), and to combine in that respect the framework,
truck, and other parts known to be satisfactory in steam locomotives at
the same time.
"This naturally required the services of a draftsman accustomed to
steam-locomotive practice.... Mr. Moore was a man of great railroad and
locomotive experience, and his knowledge in that direction was of great
assistance in the designing and building of this locomotive.
"At that time I had no knowledge of electricity.... One could count
so-called electrical engineers on his fingers then, and have some
fingers left over.
"Consequently, the ELECTRICAL equipment was designed by Mr. Edison and
his assistants. The data and parts, such as motor, rheostat, switches,
etc., were given to me, and my work was to design the supporting frame,
axles, countershafts, driving mechanism, speed control, wheels and
boxes, cab, running board, pilot (or 'cow-catcher'), buffers, and
even supports for the headlight. I believe I also designed a bell and
supports. From this it will be seen that the locomotive had all the
essential paraphernalia to make it LOOK like a steam locomotive.
"The principal part of the outfit was the electric motor. At that
time motors were curiosities. There were no electric motors even for
stationary purposes, except freaks built for experimental uses. This
motor was made from the parts--such as fields, armature, commutator,
shaft and bearings, etc., of an Edison 'Z,' or 60-light dynamo. It was
the only size of dynamo that the Edison Company had marketed at that
time.... As a motor
