The scope of wire-based communication in rail vehicles is growing. During the journey, travellers use WLAN. Passenger information systems provide users with more and more information, e.g. about the route, the nearest stations, the weather and much more. In addition, cameras increase the data stream that monitor trains, tracks and platforms.
To enable the necessary communication, trains and railcars need an efficient network infrastructure. Inside, railway vehicles are therefore equipped with the appropriate network cables. Jumper cables provide for the data flow between the vehicles – with connectors attached to their ends, which are plugged on the outside walls of the vehicles.
Space is scarce in rail vehicles
Space is scarce in rail vehicles. It is therefore important that HARTING offers plug & play connectors for the transmission of data, power and signals that occupy as little space as possible. Nevertheless, the connectors must be surrounded by robust hoods and housings and, like the cables, shielded against electromagnetic interference (EMC).
The Han® Megabit and Han® Gigabit modules are part of the HARTING portfolio for maximum data transmission rates in limited space. They enable a 360-degree-shielded transmission in a modular connector. Enclosed in large hoods or housings for outdoor use, they achieve highest data and power transmission rates per space unit.
Up to 12 Han-Modular® modules fit into the Han® 34 HPR housing. HPR stands for the High Pressure Railway series. Made of diecast aluminium, these hoods and housings meet all requirements in the railway sector. They are especially protected against corrosion, shock and vibration – with the highest degree of tightness (IP 68/69K), and fulfil the requirements concerning fire resistance according to EN 45545-3.

Expanding data networks with Porterbrook
The best example of a successful expansion of data networks in the railway sector is the Porterbrook project in England. Porterbrook leases rail vehicles to railway operators. A modern, high-performance Ethernet cabling is an important argument for operators, wagons and/or railcars to lease. HARTING supports the high bandwidth Ethernet network with EMC shielded Han® Gigabit modules, jumper cable housings and Cat 7 cable assemblies.
As a manufacturer of industrial connectors, HARTING attaches particular importance to robust and long-lasting solutions. Moreover, Han® interfaces must enable an easy and secure handling, by using coding options for instance. The respective cabling solutions have to be part of an overall concept, thus, the data connectors must be considered as a part of the overall data infrastructure of the rail vehicle.
The HARTING concept enables a smooth integration of electronic systems such as displays, monitoring cameras (equipped, for example, with M12 circular connectors) and sensors.

“Our requirement was to provide high-performance Ethernet. The pain point were 2 x 10 Gbit backbones both using ring topology networks to be fitted into one jumper cable and into another environment with limited space. The Han-Modular® Hinged Frame in combination with the data transmission modules and the M12 connector are the ideal solution for this application”, says Shane Duffy, Head of Supplier Management and Business Development, Porterbrook Leasing Company Limited.
