SUSTAINAbLE MObILITY FROM bOMbARDIER<br />

Energy-efficient trams<br />

Trams and light rail vehicles are a<br />

highly energy-efficient mode of transportation,<br />

consuming up to five times<br />

less energy per passenger than cars<br />

travelling with an average of between<br />

one and two people. At railway<br />

technology supplier Bombardier,<br />

a high value is placed on the development<br />

of cost-efficient technologies.<br />

This year’s <strong>InnoTrans</strong> featured the latest<br />

development in Bombardier’s family<br />

of trams and light rail vehicles<br />

(LRVs), the FLEXITY 2 tram. The vehicle<br />

has 100 per cent low-floor technology<br />

and conventional wheel-set<br />

bogies, resulting in an ultra-smooth<br />

service in Blackpool,<br />

ride and minimal low ground-borne vibration<br />

and noise levels. This year the<br />

FLEXITY 2 began operating in Blackpool,<br />

UK, and is currently being delivered<br />

to Australia’s Gold Coast and to<br />

Basel in Switzerland. To date, a total<br />

of 3,500 trams and LRVs from Bombardier<br />

have either been ordered or are<br />

already operating in about 100 cities<br />

in more than 20 countries around the<br />

globe. FLEXITY 2 can be equipped with<br />

energy saving technologies from the<br />

Bombardier ECO4 portfolio, including<br />

the Energy Saver, which allows energy<br />

to be re-used and provides energy sa-<br />

Efficient ticket<br />

validation machine<br />

Bavarian manufacturer ATB Automatentechnik<br />

Baumann presented<br />

at <strong>InnoTrans</strong> <strong>its</strong> new<br />

1887 Ahead ticket validator<br />

(Photo).<br />

Equipped with a new<br />

processor and co-processor,<br />

the device offers<br />

extensive and expandable<br />

memory<br />

capacities, the maker<br />

says. In addition,<br />

the unit can be operated<br />

with the traditional<br />

daisy wheel system as well as<br />

with an inkjet printer. The validator is<br />

available in several versions to better<br />

meet customer requirements, for example<br />

with a radio clock, RFID module,<br />

WLAN connection, Ethernet, RS232 in-<br />

terfaces, USB and other options.<br />

Any validator from<br />

the 1887 Ahead series<br />

can be designated as a<br />

master in order to control<br />

all the other validators<br />

as slaves in a selfcontained<br />

system. As<br />

with previous models,<br />

servicing and extensive<br />

diagnostics together<br />

with evaluation of the<br />

logbook can be carried<br />

out directly on the validator<br />

or via an external<br />

test work station. With <strong>its</strong><br />

fresh new styling and the wide<br />

range of functions, the manufacturer<br />

says, the 1887 Ahead ticket validator is<br />

equipped for the future too.<br />

vings of up to 30 per cent. The railway<br />

technology firm says <strong>its</strong> innovative<br />

wheel-set bogies result in a smooth<br />

ride and minimal track wear, leading<br />

to reduced track maintenance costs.<br />

In addition, Bombardier’s fully customisable<br />

trams and LRVs have a<br />

recyclability rate of approximately<br />

92 per cent and a recoverability rate<br />

of no less than 98 per cent (recycling<br />

+ energy recovery).<br />

Test bench reproduces wheel-rail contact<br />

Spanish research alliance CEIT-IK4<br />

premiered at <strong>InnoTrans</strong> 2012 a test<br />

bench that reproduces the contact<br />

between the wheels and rails under<br />

actual operating conditions, with precise<br />

regulation and monitoring of the<br />

relative speed and the forces being<br />

applied. CEIT-IK4 explained that the<br />

results obtained enable an estima-<br />
