Cable Liner

The Cable Liner and Cable Liner Shuttle is a range of automated people mover (APM) products designed by DCC Doppelmayr Cable Car for use at airports, in city centres, intermodal passenger transport connections, park and ride facilities, campuses, resorts, and amusement parks.

The design is notable for superseding the Maglev transport at system Birmingham International Airport which was at the time the world’s only commercial Maglev system. The technology was used for the new "AirRail Link" on the existing Maglev guideway to replace the previous system and temporary bus-service shuttle that had been operating in the mean time.

Technology and system features

The fully automated people mover (APM) systems are based on cable-propelled technology. Distances up to 4 km (2.5 miles) and a peak passenger flow of up to 7,000 pphpd (people per hour per direction) are possible.

Cable propelled

*a central station powers the system, with the cable providing tractive force
*fixed grip assembly connects the train to the cablecite web

*with the train attached to the cable by its grip, the cable can perform all essential functions such as propulsion, acceleration, deceleration and braking
*train has no on-board assemblies, such as drive engines, gearboxes or brakes

Fully automated

*no driver, conductor or on-board operator
*monitoring of system operation from central control room
*remote equipment diagnosis by means of a telecommunication link [cite book|first=DCC Doppelmayr Cable Car|title=Automated People Mover (APM): Planner's guide|publisher=DCC Doppelmayr Cable Car GmbH|date=2008|pages=39]

Evacuation system

The evacuation system is based on a completely independent stationary diesel emergency drive that pulls a stranded train back to the station in every case, which eliminates the need for an emergency walkway.

Train vehicles

*drive machinery is isolated from the environment
*noise levels along the track and in the station platforms are very low
*no emissions

Guideway

*self-supporting, steel guideway
*light steel guideway, possible through the use of lighter trains
*consists of an I-beam which forms the running and guiding surface cite book|first=DCC Doppelmayr Cable Car|title=Automated People Mover (APM): Planner's guide|publisher=DCC Doppelmayr Cable Car GmbH|date=2008|pages=35]
*guideway superstructure is a steel framework construction
*for harsh winter conditions, does not require guideway heating
*steel adapters between the steel truss guideway and the concrete columns allow height adjustments to compensate for ground settlements [cite book|first=DCC Doppelmayr Cable Car|title=References|publisher=DCC Doppelmayr Cable Car GmbH|date=2008|pages=8]
*span more than 67m (220ft)

Design

*train has same look when operated bi-directionally, middle cars are built as equal modules, end cars are mirror vehicles.
*car is a self-supporting lightweight design with extruded aluminium box-type profile sections. The integral monocoque structure is bolted and riveted, joint connections are aluminium castings.
*aluminium sections are made of high-grade, corrosion-resistant alloy .cite book|first=DCC Doppelmayr Cable Car|title=Automated People Mover (APM): Planner's Guide|publisher=DCC Doppelmayr Cable Car GmbH|date=2008|pages=45]
*the undercarriage supports are integrated into the self-supporting car body and take the form of cavity-sealed tubular steel frames.
*design is torsion-free and vehicle interior is predominantly aluminium, with a heat release of zero .

Configurations

There are four basic system configurations:

Cable Liner Single Shuttle System

*The simplest configuration, with one train operating in reversible mode on one single guideway track, with low passenger capacity and headway time demand. cite web|url=http://http://www.dcc.at/doppelmayr/solutions/en/tmp_1_847739867/Configurations_detail.aspx|title=Configurations|publisher=DCC Doppelmayr Cable Car|accessdate=2008-07-11]

Cable Liner Double Shuttle System

*The Double Shuttle System configuration is designed for system lengths up to 3km and several stations. It allows higher passenger capacities and higher frequencies (shorter headways).
*Two trains run side by side on double guideway track, each with its own haul rope and drive machinery for completely independent operation. This ensures very high system availability because even if one single shuttle system fails, the other system continues to operate.

Cable Liner Single Bypass System

*Only one guideway enters each end station, but movable switches direct trains onto dual tracks between stations so they can pass one another en route.
*The bypass must be located approximately in the middle of two terminal end stations, and can form part of an intermediate station. This configuration is comparable to the Double Shuttle System in terms of capacity and frequency (headway).
*Either each train has its own haul rope or both trains are attached to the same haul rope depending on the application requirements(station configuration, system length, etc.)

Cable Liner Pinched Loop System

*Creates a circular train flow where more than one train moves in the same direction. The principle of this system is based on several rope loops which adjoin and overlap each other in the stations. Every haul rope loop is supplied with its own drive- and return machinery.
*In every station each vehicle of the train has to be disconnected from the actual haul rope to the next haul rope in order to continue the circular and synchronized train flow. The haul rope loop change may occur only when all the trains are positioned at the standard stop position in the stations and are standstill and will be carried out during boarding/de-boarding of the passengers.
*Switches installed at the end stations will guide the train from one lane of the double lane track over to a single guideway in the end stations. During the station stop the switch will be repositioned that the train can leave the station at the other lane of the double lane track. For the functionality of the Cable Liner Pinched Loop concept the stations spans have to be approx. equidistant.
