project team, the Connectors Business Unit developed
a customrugged inter-car jumper system designed to
meet the signal requirements and harsh environmental
conditions of the project.

“TT electronics has become a valued supplier,
instrumental in enabling us to deliver this complex

and challenging project on time. Prior knowledge
and experience of the standards required by the Rail

industry was a key consideration for us when selecting
design partners and the team at the Connectors

Business Unit ticked all the boxes.”

ProgrammeManager

– RollingStock, InterfleetTechnology Ltd.

The ERTMS programme enables the speed and
movement of trains to be continuously monitored
and automatically controlled by signalling staff if

required. The project required Interfleet Technology to
fit a 19”cabinet housing the European Vital Computer

(EVC), a touch screen driver-machine interface, Doppler
radar, Euroblaise antennas, roof mounted GSM-R GPS
and Data antennas. These complex systems are
connected utilising a pre-tested, plug and play harness
assembly designed by the team at TT electronics to
reduce the vehicle downtime.

TT electronics was selected by Interfleet Technology

for its proven track record in supplying and supporting

the rail industry.Working closely with the Interfleet

Case Studies

Interﬂeet Technology–Class 158ERTMS upgrade

When Interfleet Technology was awarded the contract for the vehicle integration design
and fleet fitment of the European Rail Traffic Management System (ERTMS) tothe Class
158 Cambrian fleet, it turned to TT electronics Connectors Business Unit for bespoke
jumper and cable harness solutions.

The innovative connector features a low fire hazard

thermoplastic insulator,which is removable for
repositioning and can withstand operational

temperatures from-55˚C to +125˚C. The connector’s

IP67 rating alongside BSEN61373 Cat 1 Class A shock

and vibration classification meant it was the ideal

solution for several Petards passenger train upgrade

projects in 2011.

Effective transport surveillance systems have been
shown to increase passenger security by deterring
crime and anti-social behaviour. The installed systems

need to remain operational in fluctuating temperatures

and during extreme vibration conditions whilst
providing instant high resolution images direct to the
driver and storing them.

The team at TT electronics was able to meet these

design challenges head-on with a flexible product

offering that met the exacting standards of the rail
industry. The AB Multipole high speed & signal data
connector was selected by Petards for its simple yet
robust characteristics.

PetardseyeTrainon-trainsurveillance

Rail Vehicles

The development of any CCTV surveillance system demands high quality reliable
components matched with superior build quality. This is especially true when the

surveillance system is mounted in a challenging passenger train environment. When
Petards, the market leader in on-train CCTV solutions secured contracts for their high
performance eyeTrain digital surveillance system, they turned to the engineering
team at TT electronics for support.
