Note the hot saw in the left background. It was enveloped in sparks in
Image 10. The two sets of rolling mills are arranged in tandem, and the
hot saw is immediately behind them in this image.

No steam engine of any reasonable size could maintain a steady rolling
speed without some method of regulation. This regulation was obtained
by using immense flywheels. Each of the two steam engines that powered
this mill had a 28-foot flywheel. The flywheels stored sufficient energy to
enable the mill stands to complete the rolling of each rail without slowing
down excessively. Once the rail was outof both passes, the two steam engines
then could re-charge their flywheels with a new dose of kinetic energy.
