59 Yeoman
66 Shed
67 Skip
83 Roarer

I have only listed those which survived long enough to get a standard class number ... so the "Hymeks", "Baby Deltics" and "Warships" aren't listed.

Any to be added?  Surely there are some names for class 43 HST power car, aren't there?

Of course the original diesel class 43's were Warships although like the 52's they never carried the class number

did the class 14 ever carry the tops number in service i know the odd one has been given one now?

Yes ... of course.  Bit of inconsistent line-drawing on my part.  42 was Warship too!

Also

59 Daddy Ying
66 Ying
59 Super Shed

47s also known as Duffs and Spoons (no, me neither).

There's a page on the Renown Repulse Restoration Group's website with a very comprehensive listing of BR loco nicknames, including some multiple units as well:

http://www.renownrepulse.com/fun_stuff/class_nicknames.aspx (http://www.renownrepulse.com/fun_stuff/class_nicknames.aspx)

Some are a bit obscure but many are quite amusing!

HSTs are often referred to as Trams

I like "skateboard", referring to 153s. It's oddly picturesque.

I've heard the new Class 70's referred to as "Ducks" and "Fuglies". In that second one the 'F' stands for Freightliner, obviously!

The 153 is of course The Dog Box.. and they were out in force yesterday and for members who have yet to come across such a beast i thouroughly recommend  sampling the Weston Dog Box Experience...
The 143 is the Burger Van whilst there are loads of names for Voyagers

Hmm.... Chris from Nailsea's recent experience may rather go against that recommendation:

I quite like the nickname 'mini-cabs' for 153s. Works on two levels. First, the smaller driving position at the No. 2 end and second, they go quite fast but don't carry many people.  ;D

I think they should be called "Krytens" after the Red Dwarf character.  Anyone else see the resemblance?

A few more:

60. Politicians (you can see right through them)
91. Electra
180. Della (Adelante)
319. Bi's (from bisexual because they're AC/DC)
321. Dusty Bins (think about it.....)
323. Zoidbergs (no idea)
444. Arkwrights (again, think about it....!)
450. Doodlebugs (when they reach London they stop whining*)
460. Darth Vaders (because of the front end shape)
Network Rail's New Measurement Train (http://www.translationdirectory.com/images_articles/wikipedia/railroads/The_modern_Flying_Banana_the_Network_Rail_New_Measurement_Train.jpg). Flying Banana

*But many of the passengers, particularly if they've come from the Pompey area, will continue whining!!!!

Dr Zoidberg from Futurama, possibly due to the eyes? Pretty tenuous I'll admit.

possibly due to the sounds they make

153. Tin rocket
142/143. bendybus, nodding donkey, rickshaw
47. sh1t
121/122 bubble
150/1 strokers (i.e. 150 stroke 1)
57 bodysnatchers (all the bits from other loco's)
50 dubdub, vac.
16x turdbo.

I'm sure I read once that 153s were also referred to as tombstones or gravestones as 1-carriage trains appearing on your local line was a sign it was doomed. Fortunately that hasn't been the case yet.

On a slightly different note, some lines have nicknames. Waterloo-Exeter was known as the Mule due to the fact that there was a lot of jointed track so you could hear a clip-clop sound all along the line. I think most of it's now continous welded rail so you don't get that anymore. I think Taunton - Reading (the Berks and Hants) was known as the Desert due to the fact it passed through largely empty countryside.

I've also heard them referred to as "coffin nails", by the same reasoning!
