designation for the locomotive. Numbers, in place of names, became
widespread right after the war.
||The wheel arrangement. 4x4x0 indicated 4 wheels forward
(on a truck), 4 central drive wheels, and no wheels under the cab. This
system of designations did not originate until the 1880's.
||The date built or first placed in use on that road. Most
sources do not indicate which date they used. The intent is to show the
age of the locomotive.
||The company that built the locomotive. Most names are as
found in the Annual Reports and may not be the exact name the builder
was using at the time. Builders had frequent name changes that were not
reflected in their customers' documents.
||The weight, in tons, of the locomotive alone.
||The first number is the diameter of the cylinder, the
second is the length of the stroke.
||The diameter of the drive wheels.
||The flat bar (also called flange or strap), U-rail, or T-rail on which the train rode.
Weight is in pounds per yard. The mileage given is the road's TOTAL
length -- main line, sidings (where known) and branches.
||The "nails" that held the rail to the ties.
||U-shaped iron pieces that held the rail. Where chairs were
used, the spikes were driven through holes in the chair. Some roads used
them on every fourth tie; some used them only at the ends -- where two
rails were joined.
|End plates/Fish plates
||Horizontal plates bolted to the sides of rails to join two
rails together. Some roads used plates, some used chairs, some used
||The wooden cross pieces on which the rail rested. Ties
were about twice the gauge in length (ie 10 feet) and about 9 inches high
and wide. Ties were about 2 feet from the center of one to the center of
the next one.
||The distance between rails -- usually 4 feet 8 inches or 5
|Locomotives or Cars
||The number of Locomotives or Cars owned by the railroad
when the war began. Leases and rentals are included in the second number
and are included on the detail pages, where known.
Locomotives named are all those owned or leased
