The Suburban Railway in the Bronx
The 133rd St station was the first station and opened on May 17, 1886. All the original stations in the Bronx were built with single-island platforms with one station house and entry stairs at the designated street. The 133rd, 138th and 144th St stations were all located on the Suburban RR PROW. The structure aand stations North of 145th St were all located on Third Ave.

Also in 1815 the 149th St station was expanded to a three track two island express station as shown on the right.
All of the stations below 149th St were were double-decked in the 1914-17 express track upgrade where the upper level platforms were for express trains.
The 133rd St station (below) appeared in this format in 1941 after the Major Deegan Highway was completed to the new Triborough Bridge. The station was located between 133rd (left) and 134th Streets. However, 134th St was obliterated by the highway construction.
The upper and lower level tracks were connected by a ramp in between the 138th and 143rd St stations. The connection was used infrequently until 1954, when the center track at 149th St was taken out of service to convert the station to a terminal. The view on the right shows the upper level ramp junction looking North from the 139th St
