METRO RAIL DESIGN CRITERIA SECTION 9 / SYSTEMS

DE304.09 9-14 Revision 4: 05/09/12

Metro Baseline Re-Baseline: 04/29/10

3. Connections to Fare Collection Equipment

Connections from the power panel and the station communications room or

the cabinet at locations of TVMs and SAVs shall utilize one of two options

below, Connections from same at locations of fare gate consoles shall utilize

underfloor duct only.

a. Conduit Stub-ups

If conduit stub-ups are used (as opposed to underfloor duct), conduit stub up

for power (1" Branch Conduit) and communications (2” Branch Conduit for

TVM; 1” Branch Conduit for SAV) shall be installed in the center of each

TVM/SAV footprint. Conduit stub-ups at TVM and SAV locations should be

sealable with removable threaded metal plug inside metal female conduit

coupling that is flush with the finish surface. Conduits stubbed into the SAV

footprints shall be orientated to fit within the 4” x 6” base opening of the SAV

(6” side parallel with the 14” width of the SAV) centered within the SAV

footprint. These requirements shall also apply to spare TVM/SAV locations

(locations with provisions to install additional machines in future).

b. Underfloor (Under platform) Raceway System

An underfloor raceway system shall have separate power and

communication conduits (ducts) going to each TVM, SAV or fare gate

console. Raceways shall be embedded in the floor to support all initial TVM

SAV and fare gate console locations, as well as allowance for future

additions of TVMs, SAVs, and fare gate consoles. Cover on underfloor duct

and conductor fill shall be implemented per NEC requirements,

One end junction box shall be positioned directly above the pullbox in the

slab to facilitate pulling both power and communication cables from the pull

box in the structural slab into the underfloor raceway system for later

connection to the fare collection equipment above.

Underfloor duct risers (aftersets) at TVM, SAV, or fare gate console

locations shall be installed in the center of each TVM,SAV,or fare gate

footprint, one from the communications duct and one from the power duct.

Each riser shall be sealable with removable threaded metal plug that is flush

with the finish surface.

For conductors run on common conduit or raceway, two additional

guidelines shall apply. The voltage insulation rating of all conductors shall

match the highest insulation rating. Wires for conductors in common

raceway shall be shielded type wires.

4. Electrical

Power conduit shall be installed to run power circuits from the station power

panel to each TVM, SAV, and fare gate console location, and to the station

communications facility. Conduit shall utilize intermediate power pull boxes
