Diesel or electric, ZF innovation offers efficiency and cost savings

Interest is expected to be high at Railtex 2015 when ZF showcases the technologies behind two innovative transmissions that offer improved performance along with significant fuel and energy savings.

Steve Brew, Project Manager Sales and Technical Acquisitions for ZF Friedrichshafen AG, will be presenting the latest results of a trial for South West Trains and Porterbrook Leasing which returned savings averaging 17% in diesel fuel costs.

The reduction was achieved when conventional hydrodynamic units on a two-car Class 158 DMU in passenger service were replaced by two ZF Ecomat Rail automatic reversing transmissions.

The six month trial showed not only major fuel savings but also a notable reduction in lifecycle costs along with significantly less oil waste, the release of cooling system capacity and an improved customer experience in ride comfort.

Steve will be with the ZF Services UK team on Stand L41 for the show, 12 to 14 May, at Birmingham’s NEC. He will also be highlighting the findings to delegates when he presents a 30-minute seminar on the first day, starting at 11.05am, titled Repower with ZF.

Also creating excitement will be ZF’s Get2 Rail Drive concept, the world’s first multi-speed transmission for Electric Multiple Units (EMUs). It features the addition of a second, starting gear which when coupled with other ZF advances can deliver energy savings of up to five per cent.

The reduction in consumption and lifecycle costs, with no loss of passenger comfort, put the Get2 concept significantly ahead of conventional EMU drives with their fixed gear ratio.

The advantages of Get2 are particularly noticeable when the train is setting off. This makes it well suited to metro lines, where the distances between stops are relatively short and the train has to regularly slow down and start up.

ZF is confident the concept will be a trendsetter as transport companies, faced with rising electricity prices, focus increasingly on maximising efficiency.
