and NI Railways. The 32 were ordered after the economic boom with 2 extra ordered by NIR from their supplier EMD; the first one was delivered in 1994 after being flown from London, Ontario to Dublin Airport by an Antonov An-124 Ruslan, with the rest of the class arriving by ship in the following months.

Mainland Europe

With the locomotives proving successful in the UK, interest came from railway operators in continental Europe. General Motors locomotives in mainland Europe had historically been produced under license by local manufacturers. The high haulage capacity and reliability of the Class 59 (JT26-CW-SS) had led to its use by the German company '' Häfen und Güterverkehr Köln'' (HGK). The first mainland Europe order also came from HGK, for two locomotives, followed by TGOJ Trafik (') in Sweden. Subsequently, many European railway operators bought locomotives.

Class 77

With a high number of orders, EMD modified the locomotive for European ECR operations, including: *Powered by a 12-cylinder 710 engine that meets EU Stage IIIA emissions regulations, via latest EM2000 control system *DC traction motors, rated at *Enhanced gear case, which increases tractive effort to , making the locomotive suitable for heavier European trains *ECR Train Protection System allowing for immediate certification for operation in France, Germany and Belgium, but meaning that they cannot operate in Great Britain *Additional driver facilities, including cab air conditioning; a microwave and 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

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

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 and the ETCS Level 2 "A15" route linking Rotterdam to the German border.. The MRCE locomotives were sold to Beacon Rail in 2015. Commencing in 2015, 15 locomotives owned by Ascendos Rail Leasing and 10 locomotives owned and operated by Crossrail Benelux were equipped with ETCS.

Idle reduction

As a fuel-saving and wear-reduction measure operator DB Schenker Rail UK is to fit ninety of its fleet with automatic engine stop start technology by the end of 2015. The modification is provided by ZTR Control Systems of London, Ontario and is expected to reduce engine running hours by about one-third.

The locos were initially given a temporary certificate for use in France, and full certification came in 2009 (they had previously operated in France on some routes), Romanian certification came in 2007 The class is certified for operation in Germany, the Netherlands, Luxembourg, Belgium, Sweden, Norway, Poland and Denmark. As of 1 January 2009, certification for use in the Czech Republic and Slovakia was pending.
