Most of those I've seen have the new format registration numbers, but
I've seen 2 on route 149 that have ex-RM registration numbers, why is
that? And is it a quirk of how these registrations are issued that
within blocks, some registrations are missing between consecutive
fleet numbers.

A number of operators have retained RM registrations as cherished
plates. They are fitted to a range of buses including Volvo double decks
as well as bendy buses. Gaps in the numbers are explained above.



The gaps in the registration numbers I was referring to are for
example:
MA53 BX04 MYZ
MA54 BX04 MZD

MA62 BX04 NCF
MA63 BX04 NCJ

As I don't have a complete list, I can't tell whether the missing reg
nos (MZA-MZC and NCG-NCI) are used elsewhere, NCI probably doesn't
exist.

MZA-MZC at least are not listed as PSVs on my database.

The DVLA now have all sorts of odd rules about registrations they don't
issue as a matter of course and which are retained for sale as 'select
marks'. For example, a mark such as BX04 MYX would be retained as all
marks with the same last letter on both letter parts , in this case the
X, are retained (if that makes sense?) They appear to make other rules
up as they go along but I'm sure there must be a system. They may have
even issued them randomly to the operator as now seems to happen.

Letters I and Q are not used at all although in a break with past
practice, Z is now used but only for the second letter group, the serial
portion.

Operators in the main seems to have given up with keeping any pretence
of consecutive registrations and just use what they are given at the
time. Going back to the original point of using former Routemaster
marks. Companies seem to like to retain the links with the past and
re-use these, now historical marks. Most (if not all) these vehicles
will have been originally issued with a conventional registration, ie.
Arriva London's T7 was re-registered from LJ08 CVY to 7 CLT which used
to adorn RM1007 in a past life. MA61 which now carries 361 CLT
(originally from RM1361 which now carries VYJ 808) was re-registered
from BX04 NBL.

I believe that is explained by First Group adopting a national numbering
scheme which caused First London to change the lettered codes and then
use the national 5 digit numbering scheme.

example:
MA53 BX04 MYZ
MA54 BX04 MZD

MA62 BX04 NCF

registration plates no longer follow a consecutive series so it is
perfectly feasible for there to be gaps. The reg series for the Arriva
artics does look a bit all over the place from checking in the LOTS
Fleetbook.

http://www.lots.org.uk/ and click on publications..

If you search on http://www.buslistsontheweb.co.uk/ and look at Chassis
list and click on Mercedes and 530G you'll get all the bendy buses
including reg numbers.




Thanks Steve and Paul, some intersting links there.
