[CH] SBB orders 47 new locomotives for infrastructure maintenance and service [updated]

SBB Aem 940, that will be the designation of a new generation of hybrid locomotoves for the Swiss railways (SBB). Yesterday, they made public that Alstom is going to deliver 47 electro-diesel shunting locomotives (pantograph + combustion engine) for infrastructure maintenance and service purposes. The machines will be built by Alstom Schienenfahrzeuge AG from Neuhausen am Rheinfall (CH). Delivery will commence in 2018. (Alstom)

The Aem 940 will be of a new design. Alstom has released a spec sheet of a four axle locomotive of a mid cab design. The concept is being referred to as ‘H4’. Surely it will share components with the H3 that is currently being built by Alstom in Stendal (DE). The Aem 940s will replace SBB’s Am 841 diesel locomotives from the 90s and the remaining Ee6/6II machines from the 80s, that are being used at Lausanne Rangierbahnhof.

At the same time, SBB decided to order 35 light duty machines for maintenance purposes by Windhoff Bahn und Service GmbH Anlagetechnik. These will be multi engine diesel loco tractors. The orders combined have an order volume of Sfr 265 million. (Alstom)

[CH] Alstom to supply 47 ‘Prima H4’ locomotives to SBB Infrastructure

Alstom has been awarded a €175 million contract to supply 47 dual-mode locomotives to SBB Infrastructure, responsible for operating, maintaining and developing 3000 km of Switzerland’s railway infrastructure. The locomotives, to be used for track works on SBB’s rail network and for shunting in the shunting yards of Lausanne Triage and Limmattal, are scheduled to enter commercial service in 2018. The 47 locomotives will be manufactured on Alstom’s site in Belfort, France. The project management will be carried out in Switzerland.

The locomotive for SBB Infra belongs to Alstom’s new Prima H4 dual-mode platform for shunting and track works. The locomotive runs at speeds of up to 120 km/h which allows easy integration into mainline traffic flow. The Prima H4 bi-modal locomotive is powered by an electric traction system and two diesel generators. The two power generators, coupled with an automatic start-stop system, enable a 20% reduction in fuel consumption compared with a single engine diesel locomotive. The locomotive has been designed to optimize maintenance cycles, thus reducing life cycle costs. It is fitted with ETCS.

Particular attention has been paid to the design of the driver cabin. The large cabin (up to 4 people) has been conceived as a “working and waiting space” as track workers will not only be travelling aboard the train, but also spend time in the cabin while working on construction sites. The cabin is equipped with an HVAC (heating, ventilation and air conditioning) system and storage space for the personal belongings of the train crew. It is also protected against vibrations and air pressure when entering tunnels.

“Alstom has been the best to fulfil the award criteria of our public invitation to tender. The new and more powerful vehicles will allow us to cope with the increasing construction and maintenance volume with less vehicles and in a more efficient way. Thanks to its improved energy efficiency, Alstom’s Prima H4 will allow SBB Infra to reduce its CO2 emissions by up to 6,000 tons per year,” says Désirée Baer, Member of the Managing Board of SBB Infrastruktur.

“We are pleased to have been selected by SBB Infra for this important contract. With Alstom’s Prima H4 locomotive, which is derived from a modular concept, SBB Infra will see its operating, energy and maintenance costs reduced,” says Herman Van der Linden, Alstom Managing Director in Switzerland.
