Description

Numbered from BB 66001 to BB 66318, the locomotives were 14.898 m (48.88 ft) long and weighed 66–67 t (65–66 long tons; 73–74 short tons). Powered by an MGO V16BSHR diesel engine developing 1,030 kW (1,380 hp), they had a maximum speed of 120 km/h (75 mph). They were intended for shunting and trip working. Though designed as a mixed traffic locomotive, they had no provision for train heating and could be seen working with boiler vans on passenger services. With the general introduction of electric train heating they were relegated to freight work.[1]

Under the original SNCF numbering scheme the first 80 locomotives were numbered 040 DG 1 to 040 DG 81.[2]

Incidents
  • BB 66010 was withdrawn after a head-on collision on 15/10/81 with BB 67622.[2]
  • BB 66132 was withdrawn after a collision on 29/09/73 with BB 66126 at Trappes.[2]
  • BB 66247 was withdrawn after a fire on 12/01/1988, at St Denis-Jargeau.[2]

Rebuilds

11 members of the class were rebuilt in the early 60s with a more powerful engine and designated Class BB 66600.[2]

Between 1985 and 1989, 34 locomotives were regeared for higher tractive effort and designated as Class BB 66700.[3]

From 2004 some 91 members of the class were rebuilt with new MTU engines and reclassified as BB 69200.[4]
