But the diagrams were demanding and resulted in poor availability. Their duties on these services were taken over by Class 47/7's with Mk 3 coaches and a DBSO in 1980 and the 2 sub classes reverted to 27/0. In 1984 the class was gradually withdrawn until the last examples were taken out of traffic in 1987; 8 preserved :usertrack:ttuse:download_15_.jpg

Picture showing the cable and socket on 40 135 for the Blue Star multiple working system. The socket on the left is for the cable from the other locomotive,

the cable on the right would connect to the other locomotive thus completing the circuit for full multiple working (Along with Control Air Pipes for most loco's).

Notes

- Early Diesel Locomotive classes could be notoriously difficult to work in multiple due to the number of manufacturers and the different systems each one used (Usually requiring a driver in each loco).

- As time progressed however the "Coloured Symbol" system was introduced (Displayed on each end of the loco) allowing loco's from different classes but within the same "Code" to work together in multiple with a single driver. Some manufacturers using the eventual Blue Star electro-pneumatic MW system and others the Red Circle electro-magnetic MW system for example.

- Modern day practice does not see quite so much multiple working but allows for more Push/Pull type operations with the TDM or AAR systems.

- Older Locomotives such as the Class 20's and 37's owned by DRS for example can be seen working in multiple to this day, particularly on Nuclear Flask Trains.

- BR Policies had changed by the late 1960's. The National Traction Plan of 1967/68 decreed that all classes of locomotive should be Diesel Electrics, with the number of classes reduced to 15 from 28 by 1974. This spelt the end for the Western Region's Diesel Hydraulic classes which were now considered non standard. Only the Westerns soldiered on until early 1977. The rest had started to be withdrawn as early as 1967 with the majority all gone by 1975.

- The more unreliable and expensive to maintain types (Mostly built by North British and Clayton or BTH) were also pruned and had all gone by the end of 1972. This left a few reliable Diesel Electric classes but even then there were to be more cuts to services with the ever increasing loss of freight traffic to road vehicles; thus seeing a decrease in demand for use in locomotives.

- By the late 1970's both diesel and electric traction were under threat with Classes 24, 40, 44 and 84 the first to start a long line of withdrawals that lasted until the mid 90's prior to the privatised railway. With investment down and a shrinking market share the aging fleet of mainly 1950's and 60's built loco's diminished drastically throughout the early and mid 80's with many well known classes facing the scrapman's torch although many were saved for preservation.

- The big BR works also started to feel this pinch with famous locations like Swindon closing in 1987. Even the mighty Crewe works has now been consigned to the history books with only Derby Litchurch Lane remaining as the sole major workshops still building new rolling stock in the UK.

- With the advent of privatisation came new thinking. Ed Berkhardt's purchase of Mainline, Loadhaul and Transrail freight companies and re-branding to EWS (English, Welsh and Scottish Railway. Now DB Schenker) saw purchases of new locomotives from US giant EMD at their London, Ontario plant in Canada. The first of these was the Class 66 which in reliability terms were streets ahead of anything previously built in Britain. Next were the Class 67's built in Spain, used on Postal services. In the passenger market Virgin ordered Class 220 and 221 Voyagers from Bombardier (Now Alstom) of Canada for the Cross Country franchise (Now Arriva) and for the WCML (Now Avanti West Coast) Italian designed tilting Pendolinos. Various companies have now bought the Class 66 design such is its versatility, however with the production line now closed some companies are looking at rebuilding older designs with new equipment ie GBRf Class 69.

- Britain however still got a look in with many new DMU and EMU designs coming from Bombardier (Now Alstom) at Derby based on the successful Turbostar and Electrostar designs. Siemens in Germany have won big orders with SWT (Now South Western Railway) replacing all the old slam door stock with the Desiro which has proven to be a very reliable and popular unit and 25Kv AC versions have also been built for various operators as well as the diesel Class 185 for TPE.

- In to the future we will now see overseas manufacturers like Hitachi of Japan, CAF in Spain and Swiss manufacturer Stadler, designing and building the new IEP trains which have replaced the venerable and arguably best design from BR, the HST and Class 91 and Mk IV stock. With others like Siemens still able to produce good quality trains in short periods of time. Bombardier (Now Alstom) however will still have a shout with the recent award of new trains now built and delivered for Cross Rail (Elizabeth Line) and Greater Anglia, C2C, London Midland and South Western Railway and also new LUL stock some of which has already been delivered. Stadler have now won orders for Greater Anglia, Merseyrail, Tyne and Wear Metro, Transport for Wales, Rail Operations Group and GBRf.
