New Class Series 700/800 etc

[Haydn1971]

I'm sure it's been discussed before, the seems some logic in the use of the 800 series numbers for a train that can be either electric or electric and diesel powered, there also seems some logic on starting a new series 700 for EMU's as the 300/400 series is getting a tad used up, but what I don't get is the use of the 345 number for the Crossrail units, except for it logically following on from the unbuilt 341/342 units, but then that logic doesn't apply to the numbering of the 395. So, anyone shed anymore logic ?

They were allocated before the new ranges were announced (2012). The planned new ranges are.

• 600 - New DMUs
• 700 - New EMUs
• 800 - High Speed (200km/h+) stock

Crossrail has long claimed 345 for their units. Similarly 374 was allocated to Eurostar a long time ago. Not sure where 387 fits in but suspect that's a fudging as the 377 variants are numerous.

Classes in the new ranges also have six digit vehicle numbers instead of the usual five digits (except the 374 which has 11 digit UIC numbers for operating on the continent)

Great ! Thanks

Are the vehicle numbers in the same 6xxxxx, 7xxxxx, 8xxxxx range as the unit numbers?

They all have longer UIC numbers but may choose to only show the abbreviated version if not operating internationally.

Some might be, but not automatically.

The Railway Group Standard shows the details in table A2,
individual vehicle number ranges are as follows:

DMU - 0100000-0299999
EMU - 0300000-0499999
DMU (high speed) - 0500000-0699999
EMU (high speed) - 0700000-0899999

The leading zero would not normally be shown.

387/1s apparently have displayed vehicle numbers in the 42nnnn ranges
421101-129 DMSO
422101-129 MSOL
423101-129 PTSOL
424101-129 DMSO

It would be so much easier if vehicle numbers were all 8-digit. Could simply have the unit number followed by a two-digit vehicle ID.

I agree, it does seem a little odd that the new scheme doesn't clearly separate vehicle and unit numbers. While I'm certain that the professionals involved will cope ok, it just seems like it would be much easier or more sensible if the possibility for confusion between the 2 types of number was eliminated going forwards.

The Class 700 do give carriage number and unit number in a sense. The 700s are formed of

DMCO - 401xxx
PTSO - 402xxx
MSO - 403xxx
MSO - 404xxx*
TSO - 405xxx*
TSO - 406xxx
TSO - 407xxx
TSO - 408xxx*
MSO - 409xxx*
MSO - 410xxx
PTSO - 411xxx
DMCO - 412xxx

* 12 car only. So technically the 8 car 700001 B end cab carriage number is actually 412001, number wise the '12th' coach.
