1. A railroad system comprising:
on-board devices installed one-to-one in a plurality of trains; and
an operation management device to manage operation of a subject train that is at least one of the plurality of trains, wherein
the operation management device includes:
calculation circuitry to: calculate a target arrival time at which the subject train is to arrive at a next station, upon occurrence of a delay of a preceding train in arriving at the next station, the preceding train being a train among the plurality of trains and running ahead of the subject train; and, upon arrival of the preceding train at the next station, thereafter, calculate a target arrival time at which the subject train is to arrive at the next station; and
a transmitter to transmit, to the subject train, information on the target arrival time calculated by the calculation circuitry, wherein
each of the on-board devices includes:
a receiver to receive the ter et arrival time from the operation management device;
a storage to store information on a plurality of run curves representing changes in running speed from a previous station located immediately before the next station to the next station; and
a processor to determine a run curve suited to the target arrival time from among the plurality of run curves, on a basis of the target arrival time received by the receiver.
