Low-emission engine certified

MTU'S low-emission 12V4000 R33 locomotive engine has received US Environmental Protection Agency Tier 2 emission standard certification.

The 2 250 hp engine is optimised for rail use, and equipped with MTU's second-generation common fuel injection, water-cooled exhaust and turbochargers, and advanced control electronics.

'This is the first time EPA has certified to Tier 2 emission limits a stand-alone, high-speed engine for use in locomotive applications,' said Doug Berry, MTU Detroit Diesel Rail Sales Manager. 'Certifying the engine itself, instead of the locomotive as a whole, provides manufacturers and operators the flexibility to use this engine in any locomotive application, whether for re-powering or new construction.'

Right heights for high speed

CALIFORNIA High Speed Train Project programme manager Parsons Brinckerhoff is using NEXTMap 3D digital elevation models from Intermap Technologies in the design of the state's proposed high speed rail network (p561)

GIS mapping datasets and elevation models based on proprietary interferometric synthetic aperture radar will be used by the regional consultancy teams in preliminary environmental and engineering studies and for right-of-way preservation analysis.

Data can be exported to CAD applications to permit rapid sharing of information, and is 'considerably less expensive' than gathering custom information for the project.
