Exhibition review Hitachi selects MTU for IEP engine contract


ITACHI announced on September 19 that it has selected MTU as its preferred supplier for the contract to supply and maintain 250 700kW diesel powerpacks for Britain’s Intercity Express Programme (IEP) train fleet. MTU will supply a

specially-designed powerpack built around its 12V 1600 R80L engine, with Selective Catalytic Reduction (SCR), induction generator, and Capos starting system. The contract is worth more


than ƒ200m, and includes maintenance for the full 27.5-


year term of the train service provision agreement signed in July between the Agility Trains consortium of John Laing and Hitachi and Britain’s Department for Transport. Hitachi Rail Europe CEO


Waggonbau Niesky launches quiet bogie P


Mr Alistair Dormer told IRJ at InnoTrans that the series 1600 has completed 1000 hours of testing on a test rig at Hitachi’s Kasado plant in Japan, and that the contract will be finalised this month. Dormer also revealed that Hitachi will announce its preferred braking supplier by the end of the year.


Pesa Gama goes the last mile


ESA, Poland, revealed its new Gama range of


modular locomotives, which will include diesel, electric and dual-mode variants. The first locomotive, designated 111Ed, is a 5.6MW 3kV dc Bo-Bo unit equipped with Pesa’s Marathon last-mile diesel engine system, which allows it to operate over limited distances on non- electrified lines. The locomotive has a starting tractive effort of 300kN and a


Waggonbau Niesky has developed a new range of bogies for freight wagons which aim to reduce noise and lower long-term maintenance costs.

The DRRS25 can be fitted with conventional, compact or disc brakes, and all configurations use double rubber rolling springs instead of standard steel springs to help reduce noise resulting from the condition of the track. The disc-braked version reduces noise to 6dB(A) below the TSI Noise standard, and reduces the perceived noise level by 30% compared with a conventional wagon. Noise-based track access


charges will be introduced in Germany by DB Networks from next year and other countries, notably Switzerland, require wagon noise to be managed and reduced. This means the market for quieter bogies could be very large.

maximum speed of 160km/h. The range will also include a 2.2MW 160km/h diesel locomotive, a 160km/h multi- system model for freight operations, and a 190km/h passenger electric version. The locomotive is certified for operation in Poland, and Pesa says it is in discussions with a number of potential customers, including Polish open-access operator Lotos Kolej and several German operators.


Durmazlar Silkworm emerges in Berlin


ERMAN Rail (DB) wagon producer DB


DB claims disc brakes will


reduce maintenance costs by 35% because wheel rims are not worn down by braking, nor is there the risk of wheels overheating due to brakes not releasing properly. DB Schenker has tested the bogies as part of a DB project to develop low-noise freight trains and the bogies meet the relevant TSI standards for freight wagons.


The DRRS25 bogie is designed to comply with UIC standard UIC 510-1, meaning it is interchangeable with the standard Y25 type. Swiss intermodal operator Hupac is planning to test the new bogie under its wagons. Meanwhile Tatravagónka Poprad, Slovakia, has also developed a disc-braked bogie although it has chosen to fit them to the industry-standard Y25 design which uses steel springs for suspension. These new Y25 bogies will be tested by German wagon leasing company AAE.

Durmazlar has built two five-section 27.8m-long unidirectional prototypes, one of which is undergoing dynamic testing on the tram network in the Turkish city of Bursa. The company says it hopes to complete certification of the vehicle this month.


The prototype Silkworm is equipped with four 100kW traction motors, allowing it to climb an 8.2% gradient when fully-loaded and is capable of operating at up to 50km/h. It can negotiate 18m-radius curves and accommodates up to 282 passengers, 58 of them seated.


Durmazlar plans to offer the Silkworm in a variety of unidirectional and bidirectional configurations.
