Without a yard, every train that comes into the terminal has to go back out -- on the single track available in that direction -- to make room for subsequent trains. The bottleneck is the single track heading away from the terminal.In some cases, an extra track might have benefits. For instance, if dwell times at a particular station are very high, a second track would permit two trains to be in the station at once. But isolated situations like that don't need an extra track along the entire line. |
