GBMRG Posted January 19, 2013 Share Posted January 19, 2013 Good day all, A thought came to mind the other day where a number of BR electric locomotive classes can work together. There is plenty of evidence of this on the internet, etc. My question is whether the Class 90 locomotive specifically has worked in multiple with other members of the class as I have not seen or heard of this. I do not include locomotives that are dead in tow. Look forward to any responses to this query with grateful thank in advance. GBMRG Link to post Share on other sites More sharing options...
mjkerr Posted January 19, 2013 Share Posted January 19, 2013 Pairs of Class 90 locos briefly worked together when they were relatively new, on metal freight workings out of Mossend, in lieu of pairs of Class 87 locos Link to post Share on other sites More sharing options...
298 Posted January 19, 2013 Share Posted January 19, 2013 81-85 & 86/0- No MU equipment, can be double manned & run in tandem, but when this happened at night efforts were made to run with the loco's front pantograph leading (if still fitted with a pair) or marshall the locos with a pan leading, to avoid sparks from the overhead dazzling the second driver. 86/3 (latterly 86/4), 87/0 & 87101- Original MU equipment, although 87101 was rarely diagrammed to work with other locos because of it's superior performance. 86/1, 86/2, 86/4, 86/6, 87/1, 87/1- retrofitted with TDM, 89, 90 & 91 from new. It is possible to have a dead loco coupled between the loco and train when propelling. 92- Within class only. The most common diagramming I can think of is pairs of 86/6's on a Freightliner, or the Ravenscraig steel trains that were often diagrammed for pairs of 87's.

Guest Phil Posted January 19, 2013 Share Posted January 19, 2013 To be pernickety, 86/0 were actually fitted with M/U before they became 86/3 http://www.flickr.com/photos/blue-diesels/4493026554/sizes/o/ Link to post Share on other sites More sharing options...
Bomag Posted January 20, 2013 Share Posted January 20, 2013 86/3 (latterly 86/4), 87/0 & 87101- Original MU equipment, although 87101 was rarely diagrammed to work with other locos because of it's superior performance. 87101 had a lower HP output than 87/0 due to the first generation thyristors used. More importantly the power curve did not apparently match which meant that relative power between it and a loco couple to it would vary considerably. On the GE section in 89/90 a pair of 86s both taking power was limited to 75 mph irrespective of what is was hauling. Link to post Share on other sites More sharing options...
298 Posted January 20, 2013 Share Posted January 20, 2013 The top speed for a pair is 80mph anyway, due to unstability in the overhead affecting the second loco. It's less of a problem for pairs of EMU's, which are allowed to run faster. Link to post Share on other sites More sharing options...
GBMRG Posted January 20, 2013 Author Share Posted January 20, 2013 Dear all, Thank you for the responses thus far. As I suspected, Class 90 locomotives working in multiple with each other seem a rare event. It also appears working with other compatible electric locomotive classes has also been limited. Many thanks once again and look forward to any more light to be shone on this query, GBMRG Link to post Share on other sites More sharing options...

Thinking about it further, on occasions pairs of Freightliner liveried 90's have been used as loadbanks for testing new electrification schemes, such as the Heathrow Airport link and at Shenfield. Here are a pair of hired in 90's with their TDM connectors joined on an Euston-Birmingham, 90029 had failed and 90026 was added to keep the set in service: There is also a Garston-Dagenham automotive train that is used to transfer Anglia 90's to and from Crewe Electric, usually as DIT but on this occasion under power: Link to post Share on other sites More sharing options...

royaloak Posted January 20, 2013 Share Posted January 20, 2013 To be pernickety, 86/0 were actually fitted with M/U before they became 86/3 http://www.flickr.com/photos/blue-diesels/4493026554/sizes/o/ And to be very pernickety, some 86/0 were multi fitted before conversion to 86/3 and some 86/3 ran around for a few years before being multi fitted. There was no discernible reason for which locos were fitted until the decision was taken to fit them all. Link to post Share on other sites More sharing options...
ash39 Posted January 20, 2013 Share Posted January 20, 2013 I saw a photo last year of two 90's working in multiple in lieu of a class 92 on the tesco express, think it was in Rail Express. Link to post Share on other sites More sharing options...
