A milestone in track laying construction
The ‘E-MT 100’ material transport unit (or hopper), manufactured by BGM GmbH in south Germany, marks an important milestone in the history of track laying, argues chief operating offi cer Axel Vonhoff.
T
he E-MT 100 features patented innovations to optimise material fl ow on the track-
laying construction site and to signifi cantly increase work performance. At the same time, the modular design of the E-MT 100 makes for lean and yet decidedly fl exible rolling stock.
Laying railway tracks normally involves a great deal of machinery; even minor projects usually require the deployment of two trainsets. As the E-MT 100 allows ballast and excavated material to be conveyed in a counter-rotating process, work processes can be completely reorganised.
The innovative hopper likewise permits two work processes to be carried out from just one operational direction – without standstills and without the need for sidings. A second trainset is no longer necessary and outage periods are reduced.
Depending on the scope of the construction project, four or more E-MT 100 units will cut
out the usual unavoidable downtimes of the past. In alternating operations, two of the hoppers continuously transport new fresh ballast to the construction site whilst the other two take care of the supply of new ballast and the removal of the excavated materials.
How is it possible to have a counterfl ow of material using just one working unit? The E-MT 100 unloads the fresh ballast via a normal ground conveyor and then the advantages of the new roof unit and bypass conveyor take eff ect. There, where ballast has just been fi lled in, newly excavated material is removed via the bypass conveyor and discharged into the end of a series of silos. In that way, the material fl ow circulates: on the ground out of the silo and back in again over the roof.
Many years of experience in track-laying and knowledge of so far unused potential have gone into the E-MT 100. The roof system, which is mechanically and easily dismantled,
can be rapidly accessed in emergencies. A second bypass conveyor allows more complex conveying variations; even the roof height is adjustable. And the innovative developments do not stop with the transfer conveyors: during travel they are automatically stowed away in the substructure of the hopper.
The modular design of the E-MT 100 is simply revolutionary: it has been conceived as a core unit to which a variety of add-ons can be attached at both ends. It can be connected in series, can function as a front or end unit and allows an optimised, unusually lean fl eet.
In all, the E-MT 100 is a huge step forward when it comes to functionality, performance and signifi cantly increased effi ciency – qualities becoming increasingly more decisive in the closely competitive sector of track-laying.

Andy Cross of Oring Industrial Networking discusses two-wire ethernet and its suitability for railway use.
Train communications: less is more W
hen dealing with train communication, there is much talk about connecting
diff erent elements such as IP cameras, wi-fi , passenger information systems, VoIP phones and so on. But as the diff erent types (and more importantly the bandwidth that each requires) become more demanding of the ethernet train backbone, then one of the less talked about areas starts to become more important: inter- car communications.
There have been a number of solutions available to establish connectivity between carriages in the past, including wireless (where issues include the cost, set-up, half duplex, bandwidth limitations, and latency); DSL (low speed, and not designed for IP video); and CAT5 (jumper cable four-pins required in the same block).
Oring Industrial Networking has come up with an innovative approach to this problem,
138 | rail technology magazine Aug/Sep 14
which is to bring proven technology from the automotive arena as used by General Motors, Honda and Jaguar to name but a few. This is two-wire ethernet.
This particular technology has been developed from the ground up with video in mind and it’s completely transparent to the user, with no latency or bandwidth degradation and in full duplex.
Oring has combined this with our existing eight-port 100Tx PoE+ switch with electrical bypass to deliver a fi rst in the industry: a EN50155 PoE+ fully managed switch operating on two wires, TPS-B3082TXET-M12-BP1.
When choosing two-wire ethernet as an alternative to the traditional method of CAT5 cabling, the benefi ts become interesting from a number of perspectives. Using TE Connectivity
as a company that produces rail qualifi ed cabling to EN50306, EN45545-2, Din 5510-2, this comparison is with the new 100G signal cable:
• O/S diameter: 3.09mm compared with 7.25mm traditional four-core CAT5 • Weight: a 50% reduction • 35% better at radius bends • Price: 50% less
TPS-B3082TXET-M12-BP1 is one of a number of exciting new products being launched at Innotrans this year.
Oring has over 65 EN50155 products available, including switches up to 10G, media converters, routers and access points.
