The diesel-electric locomotives of the BB 67000 series were built between 1963 and 1969 for the French state railway SNCF . The manufacturer of the 194 machines was the Brissonneau & Lotz plant in Aytré . Sub-types are the BB 67200 (conversions from BB 67000) and BB 67300 (partly conversions from BB 67000).
History and description
Since the SNCF wanted to end steam traction by the mid-1960s, and on the other hand not all main lines would be electrified by then , they needed diesel locomotives with high performance and large tractive power for heavy trains on demanding route profiles. Between 1955 and 1957 it therefore procured 55 diesel-electric machines of the series CC 65000 and CC 65500. The experience with these locomotives led to the construction of the externally very similar series A1AA1A 68000 and BB 67000. The former were one meter longer, six-axled and approx. 27 Tons heavier. Significant differences were the train heating and the type of engine, but the two types could be used with each other for use in double traction . The idiosyncratic design of the machines was created by Paul Arzens . The paint was steel blue with white horizontal stripes on the front, which were initially emphasized by decorative strips. In order to increase the dynamic effect, the ventilation grilles on the side surfaces were designed asymmetrically as a stylized arrow symbol. Right from the start, the locomotives were given a third top light, which is only switched on in cross-border traffic to Germany and Switzerland and has been replaced by a blind cover on most locomotives.
BB 67000
The first series of the BB 67000 was put into service between 1963 and 1968, it comprised the machines 67001 to 67124. The diesel engine developed 1700 kW at 1500 rpm, the generator driven by it supplied the two forced-ventilated traction motors with 1765 V direct current. The continuous traction power was 1240 kW. The type Y-210 “Jacquemin” mono-motor bogies largely corresponded to those of the BB 9400 electric DC locomotive . The drive took place via hollow and cardan shafts, the power transmission was provided by low-level tie rods. The gearbox was switchable from 90 km / h to 135 km / h, but the overdrive was shut down in 1975.
The “ Nez cassé ” driver's cab with forward inclined front windows (compare: CC 72000 ), which was favored at the time, was not used for optical reasons. The rounded cabin was made from a multi-layer polyester compound. The curved pane elements at the corners created an optically continuous glass front, but from BB 67041 onwards this was dispensed with in order to avoid interference from the side.
Since the locomotives did not have a device for train heating, a heating car had to be carried on passenger trains . Therefore, from 1975 onwards they were only used in freight traffic. The locomotive 67036 was equipped with a three-phase generator with silicon rectifier in 1965 and was given the new number 67291. At the output of the generator, it received a parallel tap for the electric train heating.
BB 67300
Since the three-phase generator of the 67291 proved itself, 70 machines with this technology were delivered from 1967 to 1969, they were given the numbers 67301 to 67370. In addition, between 1975 and 1979 20 BB 67000 were converted accordingly and were given the numbers 67371 to 67390. The continuous traction power increased to 1525 kW, and passenger trains can be heated by the locomotive using a generator tap. The transmission can be switched from 90 km / h to 135 km / h. From 1995 many machines were repainted in the blue or red "livery multiservices". In the winter of 2018/2019, the 67345 and 67376, the last two locomotives of this series, were parked. With the 67382 and 67305, two 67300 are preserved in a museum, the latter in the Mulhouse Railway Museum “Cité du Train”.
BB 67200
80 locomotives of the first series were converted between 1980 and 2007 in order to serve on high-speed lines for route maintenance and as auxiliary locomotives for broken-down TGV trains. They were re-classified under the numbers 67201 to 67280. Machines were selected for the main inspection and modified accordingly in the SNCF workshops in Nevers and Rouen . They received the train control system used on the respective high-speed route, and the locomotives 67231 to 67238 each received a Scharfenberg coupling permanently attached to driver's cab 1 . For use on the LGV Nord the BB 67247 to 67256 were pivotable Scharfenberg couplings, which permits the use of the conventional screw coupling on.
Successor: BB 67400
In 1967 a third series was ordered and 232 locomotives were put into operation between 1969 and 1975. It differs from its predecessors in the bogies, the brakes, the traction motors and the no longer switchable gearbox. BB 67632 was the last mainline diesel locomotive to be delivered to the SNCF on October 31, 1975. In mid-2016, 125 of these machines were still available.
