Very early on, in 1894, the TRC decided on single-ended operation. Many of the early streetcars were "open" cars, where there was benches across the width of the car and thus no centre aisle. Passengers had to board on the curb-side of the open car, and for safety, there had to be a barrier along the length of the car on the opposite side. Before the summer of 1893, there were double-ended open cars, which required two men to move the barrier to the other side of the car at the end of the line. Some open cars had one-man crews, requiring a helper to be stationed at the end of the line. Having single-ended cars with loops or wyes saved staff time. Also, both open and closed motor cars could pull one or two trailers; thus, single-ended operation eliminated the time needed to rearrange the consist at the end of the line.
