Hi
I have always been puzzled about the difference betwee the mk1,2,3 and mk4s carriages. I believe that the mk1s look different from the mk2,3,4s. Could anyone tell me the difference ?

Thanks :)

Mk4 stock is also tilt body profiled if you look at it carefully enough...the rest is just square (rectangular if you are being pedantic!)

Cheers

Mk4s won't tilt though! Needs a tilting loco and the only capable Tilting loco is the 91. Won't happen since the Wi-Fi destroyed that.

Mark 4s where built to original tilt, but the goverment wouldn't invest in making it happen.

Mark 1s and 2s have speed of 100mph (although nit pickers would quote the 110mph mark 1 BGs, and the Mark 2 in the HST test train that can do 125mph)
Mark 3s can do 125mph, be it loco hauled or HST form.
Mark 4s can do 140mph, although that was just on the short stretch north of peterborough, and was for testing purposes only, and has no ceased.

Mk1s look old. You can always tell them apart. Commonwealth bogied examples are 90 mph. B6 bogies are 100mph.

Mk2s have square toilet windows. The doors also wraparound the rear of the coach much more obviously than Mk3s. The under coach equipment is butt naked. All stock is 100 mph. Only Mk2Fs are left in official passenger service on Rhymney trains and Manchester to Birmingham New Street services.

Mk3s have a split toilet window. They have covered undercoach stuff. They have an indent in the doors under the window. They are 125 mph stock. Class 150s, 317s, 156s and so on are all Mk3 bodyshells.

Mk4s have power doors. They are 140mph stock. Class 158s also use this body (159s too).

Only mk2 "coffins-(air con stock)" have wrap around doors, the older pressure ventilated ones have mk1 style doors- (and some suburban ones have centre doors as well). There are still quite a few mk2's still on "one" services as well, including some dbso's that are being painted into the rainbow livery, and also FSR & FGW sleeper service seated coaches are mk2's.
