METRO RAIL DESIGN CRITERIA SECTION 9 / SYSTEMS

DE304.09 9-60 Revision 4 : 05/09/12

Metro Baseline Re-Baseline: 04/29/10

9.4.3.8.2 Local Route Selection Capability

Local control capability shall be provided to ensure the safe operation of trains by means of

Local Control Panels (LCP) in each signal house.

The LCP shall indicate track circuit occupancy, signal status, switch position and

correspondence, switch locking, traffic direction, manual control, automatic control, and

crossing gate position.

9.4.3.9 Wayside Signals

9.4.3.9.1 Main line

LED wayside color signals shall be provided to indicate movement authority, block

occupation and route locking information to train operators. Signals shall be installed to

govern movements into and through interlocking limits.

Wayside color signals shall show the following aspects, which are in compliance with Metro

rules:

Aspect

Meaning

Red/Red Stop

Flashing Green/Red Block clear. Proceed on normal route. Trains operating with

ATP Bypass activated shall be prepared to STOP at the next

interlocking Signal.

Green/Red Block occupied. Proceed on normal route with Cab Signals.

Trains without cab signals or operating with ATP Bypass

activated shall STOP and contact ROC.

Red/Flashing Green Block clear. Proceed on diverging route. Trains operating with

ATP Bypass activated shall be prepared to STOP at the next

interlocking Signal.

Red/Green Block occupied. Proceed on diverging route with Cab Signals.

Trains without Cab Signals or operating with ATP Bypass

activated shall STOP and contact ROC.

Flashing Red/Red STOP and contact ROC. Proceed indication cannot be

displayed. When authorized by ROC, proceed in Stop and

Proceed mode on Normal Route.

Red/Flashing Red STOP and contact ROC. Proceed indication cannot be

displayed. When authorized by ROC, proceed in Stop and

Proceed mode on diverging route.

Indication on signals or switches shall be fail-safe, such that no less restrictive aspect is

shown than intended. “Block Clear” aspects shall not be used in street-running areas.

Wayside signals shall be located such that they are sufficiently visible to preclude confusion

with signals governing the operation of motor vehicles, and similarly do not confuse motor

vehicle drivers. When viewed from a height of 7 feet above top of rail, at a distance of 500 ft,

lenses shall present a distinct aspect under the most adverse operating conditions.
