The Mezzanine level is the first level below ground, which is the public access level to the tunnel.
In some stations, an ancillary level may be encountered as the first level below the street. The ancillary level is not for public access and can only be entered by using keys found in the Fire Department’s lock box, adjacent to the EMP.
The ancillary level contains the different control rooms for the station functions, such as the Train Communication and Control Room (TCandC), mechanical room, Department of Water and Power (DWP) power station, and fan room. In most of the stations, this area is entered from the Mezzanine Level.

Each ETS contains the following:
- An Emergency Telephone (ETEL) to communicate with ROC or the EMP.
- A Fire Department telephone (FTEL)
- A diagram as to what section of track will be affected by the trip switch
- A deluge sprinkler control switch to activate sprinklers under the trains
- A trip-switch to disconnect power to a segment of the third rail.
Prior to pushing the trip switch, make sure the entire length of the train is in the station. If one collector shoe is in contact with a live section of the third rail, the entire train is still energized. The third rail carries 750 volts and can be on either side of the track. If the trip switch is pushed, a Fire Department lock should be placed through the hasp to guarantee that the third rail will not be re-activated (i.e., lock-out/tag-out).
