LOS ANGELES TO ANAHEIM

ENGINEERING ELEMENTS


LOS ANGELES TO ANAHEIM

• Length: Approximately 30 miles

» Complete HSR between Los Angeles & Orange Cos.

» Improve safety along historic rail corridor

• Proposed HSR Stations

» Los Angeles Union Station *

» Norwalk/Santa Fe Springs

» Fullerton

» Anaheim (ARTIC) *

* High-speed rail stations per Proposition 1A


VERTICAL ALIGNMENT

• Majority of corridor is at-grade

within existing rail corridor to

the extent possible

• New grade separations to

separate rail traffic from road

traffic along corridor

Photos and graphics for illustrative purposes only.


ALIGNMENT: AT-GRADE


• Majority of corridor is

at-grade within

existing rail corridor

to the extent possible

AT-GRADE EXAMPLE

Raymer Avenue at Gilbert Street, Buena Park


ALIGNMENT: BELOW-GRADE

Trench


Below-grade proposed to avoid

Fullerton Airport flight path

& to cross corridor to approach

Fullerton Transportation Center


ALIGNMENT: ELEVATED


Upgrade existing bridge to accommodate HSR Tracks at Norwalk/Santa Fe Springs Station proposed

to be in viaduct (or bridge) to accommodate HSR


GRADE SEPARATIONS

» Improved safety

» Reduced noise (no train horns)

» Decrease in traffic congestion

» Reduction in greenhouse gas

emissions from idling vehicles

» Improved train operations reliabilityA grade separation is a roadway

that is re-aligned over or under

a railway to eliminate hazards.Photos and graphics for illustrative purposes only.


GRADE SEPARATIONS

HSR Grade Separation – Overcrossing

Conceptual Illustration Only

Sample Impacts at Grade Separation

• Evaluate potential impacts associated

with grade separation elements, such as:

» Changes to roads & driveways

» Utility relocations

» Property acquisition

» Traffic circulation

» Construction-related (road detours, dust, noise)

• Avoid, minimize & mitigate impacts to

surrounding properties



• 15 Roads Currently Cross Railroad Tracks At-

Grade

» Metro is currently planning to grade separate Rosecrans/Marquardt

• HSR funding partner

» HSR is planning grade separations in coordination with local cities

• Included in environmental document (NEPA/CEQA)

• Grade Crossing Types

» New grade separations (blue) 11

» Modified existing grade separation (gray) 23

» Remain at-grade crossing (yellow) 2

» Existing crossing closures (purple) 2

BRIDGE DESIGN EXAMPLES



SOUNDWALLS EXAMPLES



• Overhead Contact Systems» Supplies electric energy to rail vehicles

• Paralleling Station

» Provides voltage stabilization and equalizes current flow

» Located every 5 miles between paralleling stations and Traction Power Substations (TPSS)

• Switching Station» Connects and balances the electrical load between tracks

» Located every 30 miles between the TPSSs

• Communication Tower» Uses a radio-based communications network to provide Positive

Train Control (PTC)

» Located every 2-3 miles

• Early Earthquake Warning System

• Intrusion Protection» e.g. fencing, walls
