fridge in one cab; additional noise cancelling insulation; a modified seat Designated JT42CWRM-100 by EMD and registered in France as Class 77, over 100 locomotives have been purchased including 60 by DB Schenker subsidiary Euro Cargo Rail. Class 66EU In 2008 EMD announced plans to develop a new variant 'Class 66EU' designed for continental European operations, built within the UIC 505-1 loading gauge as opposed to the restrictive UK loading gauge. A range of European safety systems would be supported including ERTMS, and locomotives would be fitted with a dynamic brake and previous issues with driver comfort were to be addressed. The project was confirmed to be cancelled in 2011. A similar locomotive concept using EMD technology is the Vossloh Euro 4000 and has been delivered to operators in several countries including Norway, France, Spain, Portugal and Israel. Technical The locomotive uses standard EMD components - an EMD 710 prime mover, D43 traction motors, radial (self-steering) bogies of patented design, which reduce wheel surface and flange wear and are said to improve adhesion and reduce track load. The class has undergone updates; other than the lower-geared class 66/6 produced for Freightliner, most of the updates have been in relation to conforming to specifications for exhaust particulate emissions. Despite being popular with rail operators, especially due to its high reliability, the class has not been universally successful: one recurring problem has been driver comfort. In particular, noise levels (including noise from the cab horn), vibration, and excessive cab-temperatures in hot weather have brought serious complaints. The cab is not isolated from the main frame, causing engine noise to be the dominant background noise; notwithstanding the implications for safety (audibility of warning signals etc.), and the potential for hearing damage in the long term, the conditions drivers face led to threats of industrial action in the UK in 2007, and an agreement for increased pay for drivers using this type of locomotive (in Norway). By modifying using noise absorbing materials EMD succeeded in meeting TSI Noise Certification standards in 2008. Tests on retrofitted cooling systems and improved seating have been carried out on some UK locomotives. ETCS Equipment Between 2006 and 2010, 12 locomotives belonging to Mitsui Capital Rail Europe (MRCE), operating in the Netherlands and Germany, were equipped with ETCS, principally to allow them to work on the equipped Betuweroute, comprising the ETCS Level 1 "Havenspoorlijn" in the Rotterdam harbour area
