• Various site plans include detailed layouts for locations such as Branscomb, Norwalk, Lakewood, Long Beach, Imperial/Wilmington, and Avalon.
• Each site plan features pedestrian access routes, track layouts, and key structures.

Key Components of Each Site

• Parking Areas: Each location has designated park and ride areas for convenient commuter access.
• Elevators: Multiple elevator machine rooms facilitate movement between different platform levels and public areas.
• Communications Rooms: TCCR (Train Control Communications Room) is present at several stations ensuring efficient communication systems.

Station Features

• Train Platforms: Platforms are strategically designed for both westbound and eastbound tracks, enhancing passenger convenience.
• Ticket Vending Machines (TVM): Placed in easily accessible locations to facilitate ticket purchases for riders.

Ancillary Facilities

• Electrical and Mechanical Rooms: These support station operations, with dedicated spaces for transformers and control systems.
• Emergency Stair Access: Safety features include emergency stairs for quick evacuations.

Track Access Layout

• Tracks are systematically separated into designated westbound and eastbound, allowing for smooth transit operations and preventing congestion.
• Accessibility features offer important links between platforms, enhancing commuter flow.

Plaza Areas

• Each site has distinct plaza levels (West and East Plaza) providing public gathering spots and additional services.
• Stations are connected to surrounding areas through planned roads and pathways.

Infrastructure

• FDC (Fire Department Connection) and STG (Staging Areas): Essential for safety and operational readiness during emergencies.
• TPSS (Traction Power Substation): Critical for powering electric trains, strategically located across site plans.

Site Connectivity

• All locations are designed with community connectivity in mind, integrating nearby roads, bus stations, and pedestrian pathways.
• Facilitates interchangeability between train, bus, and personal vehicle commuting options.

Key Dual-Level Dimensions

• The layouts include comprehensive levels such as street level, platform level, and mezzanine level to manage passenger flow effectively.
• Well-distributed stair and elevator access promotes efficient transitions between levels.

Additional Site-specific Notes

• Long Beach and Avalon stations feature unique designs catering to heavy commuter use due to their strategic locations.
• The overarching design of each site emphasizes safety, accessibility, and efficient transit operations across urban landscapes.
