Blocking cars
Cars moving toward common destinations can be grouped into blocks. Classification yards rearrange cars so blocks move efficiently through the network.
Managing train forces
Heavy and light cars, curves and grades affect the forces moving through a train. Railroads use train-makeup rules to manage those forces.
Distributed power
Locomotives in the middle or rear spread pulling and braking forces through a long train and are remotely controlled from the lead locomotive.
End-of-train devices
Modern freight trains generally use an end-of-train device instead of a caboose. It monitors brake-pipe conditions and communicates information to the locomotive.
Before departure
Required inspections and brake tests help confirm that equipment and the braking system are ready for the trip.
