IC225 and Class 91 commissioning - Part 1 of 9
In the beginning
During February 1988 the first of ten 'prototype' class 91 locomotives rolled out of Crewe Works on time. 91001 was the first of what was eventually to number 31 locomotives which were introduced onto the ECML. The first batch of ten locos were subjected to intensive mileage accumulation running with various rakes of ECS before service introduction. The Class 91 locomotive is a 25 kV Bo-Bo locomotive with a rated power of 4.54 MW (6,000HP) and a design speed of 140 mile/h (225 km/h) . The locomotive will haul up to 11 Mk IV coaches and a driving trailer on the electrified East Coast Main Line from London to Edinburgh. In addition sleeper trains of up to 750 tonnes were planned to be hauled on the West Coast Main Line including the arduous ascents of Shap and Beattock. The contract was placed by British Rail in February 1986. The first locomotive 91001, was the subject of a comprehensive acceptance and performance testing programme over the following months. Here is a selection of photos of the class 91 and IC225 vehicles under test and in service. Click on the picture for a bigger image - all pictures are the author's unless otherwise credited |

By the spring of 1988, loco 91002 was delivered to Bounds Green depot (BN), situated at the south end of the ECML adjacent to Alexandra Palace station and the Hertford Loop line and the remaining 8 locos duly followed as 91001 was already there. During their mileage-gathering phase they ran in turn, initially with a rake of Mk2 coaches, to Peterborough West Yard and back each day. The return trip usually terminated in Kings Cross Goods yard where a run round loop had been especially installed and electrified for this purpose. Running the loco round here avoided being 'trapped' in Kings Cross station as the stock was not at the time equipped with a DVT. We often used to wait in the shunters' cabin and have a brew, whilst a path was sorted out back to BN. Today the site has been buried under the High Speed 1 connections to and from St Pancras and to the North London line and the ECML. During initial commissioning of the first ten locos we used to run to Peterborough West Yard with a train of Mk2 coaches. |
In May 1988 class 91 No:91003 was part of a special train which was taken to Hamburg, Germany for the International Transport Exhibition (IVA88) Click on the picture for a bigger image - pictures are the author's |
The technical data for the class 91 was produced in German and English for the Hamburg IVA88 exhibition | 91003 pictured in Hamburg, Germany for the IVA88 exhibition in May 1988 |
In July 1988 a series of comparison tests were conducted overnight with a class 91 and a class 90. Not sure exactly what was being compared though. |

After initial runs to Peterborough we moved further afield to Grantham where the trains ran into the freight loop on the west side of the station. Once we arrived the loco would run round and we would bale out and leg it onto the platform and across the footbridge to the excellent privately run buffet on the Up platform. Later when the electrification was completed the running was extended to Leeds generally with Mk3 sleepers and DVT's but with the odd run with Mk2 coaches. |
