Abstract
A train information management apparatus includes a first system central device that generates first train control information for a car-mounted device in every predetermined period and a second system central device that generates second train control information starting from the time at which the time obtained by multiplying the predetermined period with 1/2 has elapsed from the time point when the first train control information is transmitted. The first system central device generates a first packet every time the first train control information is generated and alternately transmits a first packet to a first system trunk transmission line and a second system trunk transmission line. The second system central device generates and transmits a second packet almost in the same manner except that the second packet is transmitted to a trunk transmission line on the opposite side of the trunk transmission line to which the first packet was transmitted.
