21,000 new parking spaces • Enhanced Bus Network & Transit

Hubs (FastConnects) • Redevelopment of Denver Union

Station

• 57 new rail and/or BRT stations • Opportunities for Transit Oriented

Communities

Commuter vs. Light Rail • Light rail

– Lighter in weight, smaller, designed to make more stops, better turning radius and city street operation

• Commuter rail – Heavier, larger, faster, carries more

people, fewer stops, compliant for railroad corridors

FasTracks Status • West Rail Line (W Line)—First

FasTracks line to open—April 2013

• Denver Union Station—Bus Concourse opened in May; historic building in July

• East/Gold/Northwest Rail Lines (EAGLE)—67% complete

• I-225 Line—44% complete

• U.S. 36 BRT—Phase 1 of managed lanes 82% complete, Phase 2—42%

• North Metro Line—Design underway, early work in progress

Eagle P3 Project • Includes East Rail Line, Gold Line, first segment of Northwest Rail and

commuter rail maintenance facility

• First commuter rail car arrives in the fall • Opening in 2016

6

Eagle P3 Project • RTD pursued concept of P3 in

2007 – “The Perfect Storm”

• Costs skyrocketed • Revenues plummeted

• First transit P3 of this magnitude in the U.S.

• RTD retains ownership of assets • 34-year contract

– 6 years design/build – 28 years operate/maintain

• More public entities are turning to P3s to build out their projects 10

East Rail Line

• 22.8 miles electric commuter rail • 6 stations • 35-minute travel time to DIA • Complete in 2016

Gold Line

• 11.2 miles electric commuter rail

• 7 Stations • 25-minute travel time

to Ward Road • Complete in 2016

Northwest Rail Line – Segment 1 • 6.2 miles electric

commuter rail

• Downtown to Westminster at the 71st/Lowell Station

• 11-minute travel time to Westminster

• Complete in 2016

RTD Overhead Catenary System

Passenger Rail using OCS

Other systems using OCS

Stagger Stagger is the registering of the contract wire off the centerline of track / middle of the pantograph.

Track Rails

Pole & Cantilever Stagger is the distance

between the registration point and the centerline of the tracks or pantograph Pantograph

Stagger on Curves Stagger is required on curves to keep the OCS on the pantograph

Pole & Cantilever

Track Rails

Stagger must be made to the outside of the curve to keep OCS over the pantograph at the mid

span

Fixed Termination Catenary

Catenary sags as temperature rises.

RTD Traction Power

Two Traction Power Modes

Light Rail 825V DC

Commuter Rail 25kV AC

Different Style TPSS

Light Rail – Prefab Substations

Commuter Rail – Outdoor Substations

LRT TPSS • Convert Utility power to 825V dc power for light

rail • TPSS are needed about every mile along light

rail alignment – there are close to 50 on system.

• Each TPSS is typically rated at 1.5 MegaWatts.

CRT TPSS • Convert Utility power to 25kV ac power for

commuter rail • TPSS are needed about every 30 miles along

commuter rail alignment – there will be 3 system.

• Each TPSS is rated at about 20 MegaWatts.

Closed Circuit Television System • Cameras at Platforms, Parking lots, and other RTD

facilities • All IP network based • Includes; Cameras, NVRs, Video Servers at SCC

Emergency Telephone System • Emergency Telephones (ETELs) • Typically on Platforms, Pedestrian Bridges and Plaza

Areas • One Button Auto Dials Security Command Center

Public Address System • Provides Audio Mainly Under Shelters • Both Local and Central Announcement Capabilities • Ad Hoc and Canned Messages

Variable Message Sign System • Provides Visual • Both Local and Central Announcement Capabilities • Ad Hoc, Canned, and Scheduled Announcements

Radio System • Provides Voice Communications to Train Operators,

Maintenance Personnel, Supervisors, and Security Personnel.

• Data Radio – PTC WiMax

Communication System Challenges • High Visibility with Many Stakeholders • Integrating New System Into Existing (especially

software) • Continually Evolving Technology

RTD Signal System

Common Signal System Equipment • Automatic Block Signaling (ABS) • Track Circuits (TC) • Signals • Switches & Interlockings • Operations Control Center (OCC) • Grade Crossing Warning System • Positive Train Control (PTC)

Automatic Block Signals

• Signals are installed at boundaries of “blocks” • Signal aspect control train movements. Green – proceed, Yellow –

prepare to stop, Red-stop. • Safe Braking Distance – basis of block design, dependant on

vertical and horizontal curves, civil constraints , and train speed. • Signal enforcement – “Automatic Trip Stops “ are installed to

automatically stop the train if it overruns a Red signal. • Grade Crossing warning system allow safe train operation through

street crossings in high speed. • Signal system is tied into the Operational Control Center

TC2 TC3

Track Circuit (TC)

• The boundary of a Track Circuit is defined by insulated joints • An insulated joint is a physical break in the rail that separates the rail

into electrical circuits • In Signal System the rails are used to function as two un-insulated

wires • From the signal house, the transformer(T) and relay(R) is

connected to each end of rail block. • The track circuit is described in its “Normal” state with no train in

circuit.

Track Circuit is installed in each rail “block” to monitor the train occupancy

TC

Switch Interlocking

• Track switches are installed at strategic locations to allow train to switch to other tracks.

• Switches, Signals, Track Circuits are all “interlocked” to provide safe routing.

Operations Control Center

• Signal systems are tied into the Operations Control Center to enable centralized control and monitor the whole transit system

Grade Crossings • Grade Crossings protect street traffic from

LRVs or CRVs. • Signal system sometimes is integrated with

local street traffic control.

Positive Train Control • Signal system for Eagle P3 requires

Positive Train Control (PTC) • Basic components of PTC

• OCC - Server • Train - gps, vehicle status… • Radio – communication equipment

RTD Rail Vehicle Technologies

Vehicles Why Two Types of Vehicles? • Light Rail Used on Initial RTD Corridors

and Some Extensions – Largely Dedicated Right-of-Ways – Older Agreements with Freight Railroads

• Commuter Rail Now Required by Denver’s Freight Railroads to Operate in or near Their Corridors – Must Meet Federal Railroad Administration

(FRA) Safety Standards

Rail Technology Comparison

Commuter Rail (EMU) Light Rail (LRV)

Powered by 25kV AC overhead electrical system

Powered by 750V DC by overhead electrical system

Typically serves longer lines with few stations

Has a lighter frame than a commuter train

Can operate up to 79mph Can operate along crowded, narrow streets

Larger interior with more seats Can accelerate and decelerate quickly

Light Rail

• 81.4 ft long, 8.7 ft wide, 12.4 ft tall • 6 Axles, Articulated Body, Two Cabs • Low Alloy High Tensile (LAHT) Steel Body, Painted • 64 seats, 120+ standees • 90,000 to 122,000 lbs • 82 ft Minimum Horizontal Curve • 3.0 mphps Maximum Acceleration • 3.0 / 6.2 mphps Maximum Braking

Commuter Rail

• 85 ft long, 10.5 ft wide, 15 ft tall • 4 Axles, Solid Body, One Cab • Stainless Steel Body, Unpainted • 91 seats, 142 standees • 140,000 to 180,000 lbs • 250 ft Minimum Horizontal Curve • 1.6 mphps Maximum Acceleration • 2.5 / 3.0 mphps Maximum Braking

Vehicle Differences Carbody Strength: • RTD LRV’s designed to resist about 250,000

pounds coupler-to-coupler crush force, generally European crash standards.

• RTD EMU’s designed to resist 800,000 pounds coupler-to-coupler crush force, must meet FRA and APTA strength standards.

Signaling: • RTD LRV’s automatic train stop (ATS). • RTD EMU’s will use positive train control

(PTC) with automatic train control (ATC) as a backup.
