WHY CAN'T I RUN FOUR CAR TRAINS?

With the continuing growth of traffic on LRT systems, management is often faced with the dilemma of increasing throughput in terms of number of riders carried per hour on a given section. The accepted options to maximize the utilization of existng infrastructure and to meet the traffic demand are: decrease train headway, increase the number of cars per train or alternatively a combination of both. There are several factors which must be considered to minimize the impact of such operational changes, for example, substation capacities, overhead catenary system capacity, length of station platforms, adequacy of signaling systems, impact on road intersections and increased maintenance and operational costs etc. This paper discusses these factors and develops methodology to compare the impact of decreases in train headway and/or increases in the number of cars per train to accomplish the same stepped increases in traffic throughput.
