The later CAF-built Mark 4 sets include their own generators in the Driving Van Trailer (DVT).

HaslerRail 2500 Event recorder Fleet InterCity Today push-pull equipped members of the 201 class operate the only passenger locomotive hauled services in the Republic of Ireland between Dublin and Cork. They operate with Mark 4 carriages which were introduced to the route in 2006/2007. The current livery, which primarily consists of green and silver, was introduced in 2006. All locomotives have full yellow ends to enhance visibility. Non push-pull locomotives were withdrawn from service because Mark 4 carriages operate a push-pull system and rolling stock on other InterCity routes was replaced by 22000 Class DMUs. The only other locomotive-hauled service (also push-pull) is the Enterprise cross-border service to Belfast which is detailed below. Enterprise The Enterprise is a cross-border passenger service between Dublin and Belfast operated by Iarnród Éireann and Northern Ireland Railways. This is also a locomotive-hauled service and operates a similar push-pull system like services to Cork. As this is a jointly operated service, it is marketed as the "Enterprise" and the coaching stock and locomotives carry a separate livery to either operator's own services. It consists of light grey with a purple and red strip. Locomotives also have full yellow ends to enhance visibility. As the service is shared, locomotives (8)208 and (8)209 are owned by Northern Ireland Railways. The coaching stock is owned by operators, Iarnród Éireann own the odd numbered coaches and NIR own the even numbered coaches. In addition, Iarnród Éireann introduced four former Mark 3 generator vans, in September 2012, to operate this route, in a bid to improve reliability of the
