In addition there is a branch from the sub-way leading up to the approaches of the other high-level bridge, which serves the western suburbs. On theeastern side of the City Railway loop another linebranches off to the eastern suburbs, coming aboveground about V2 mile away.

On the City Railway the stations provide for islandplatforms 520 ft. long. Bifurcation of track at theplatforms has been adopted to eliminate the effect ofthe station stop on track capacity, while congestion isavoided by separating the incoming and outgoing traf-fic as it moves from the platform to the street and viceversa. A maximum speed of 35 will obtain onstraight level track and down grades, and the schedulespeed, including station stops, will be half the maxi-mum speed, or 18 With regard to the use of bifurcated tracks, thereport states that the capacity of a rapid-transit rail-way is measured by the number of trains that cantraverse a single track during the evening number of trains depends primarily upon thelength of station stops, and if the effect of
