Three weeks later, manhole covers flew into the air as underground explosions along West Pratt Street followed due to residual explosive chemicals from the fire left in the sewers.

Railroads needed better engineering of bridges and roadbeds, stronger rails, better methods for communicating, improved ways to control trains, and safer brakes and couplers.hese last two were especially important to railroad safety and are good examples of how long it took to get a good idea to be used.
The distance between the rails is known as the gauge of the track.
The rails are held to the ties by large spikes which also keep the track in gauge.
