ANOTHER Philadelphia & Reading engine with Wootten's boiler
and firebox was this 4-2-2 type built the same year as the 4-4-0.
It was also designed for high-speed passenger traffic and intended
for use on the two-hour trains over the Bound Brook Line between
New York and Philadelphia.
With this wheel arrangement, coupling rods were dispensed with,
and to eliminate an excessive load on the drivers a system of
equalizing levers was provided. Movable fulcrums controlled by
a steam cylinder permitted a greater weight to be applied to the
drivers when starting, and when running the excess weight could
be transferred to the trailing wheels. This allowed the total
weight distribution to be equalized.
This engine was later resold to the Eames Vacuum Brake Company
of Boston and it was sent to England to demonstrate this brake
