Wednesday 25th February 2009 ~ What Does It All Mean ?

A few people have asked me recently about the codes used referring to the X1 car lines. Well for those interested you can go to :

On this page you will find a link to the M-F timetable and diagrams.
One thing I used to find handy when following trains was that one could usually predict pretty accurately what a loco would do the following day. This is something which is almost impossible with buses, but recently a pattern has emerged with the X1 terminators at Yarmouth. This is best explained as follows :
K1 arrives YAR 20.25 - does either J10 or Y21
K20 arrives LFT 00.37 - does either J10 or Y21
K5 arrives YAR 19.25 - does Y14 07.32 Yarmouth - Lowestoft
K6 arrives LFT 22.37 - does Y8 06.02 Yarmouth - Peterborough
It is strange that two turns which terminate at Lowestoft then go empty to Yarmouth, but there you are.
Turns which terminate at Lowestoft and overnight there are the following
K16 arrives 18.10
K18 arrives Gorleston 19.00
K2 arrives 21.37
Y9 arrives 23.37

These four turns are used indiscriminately next day on
Y9 06.32 Yarmouth - Peterborough
J11 07.05 Gorleston - Peterborough
L12 07.15 Lowestoft - Peterborough
L13 07.45 Lowestoft - Peterborough

With this in mind I am planning to change the prefix on turns 9,10 and 11 which I have used since the inception of the X1. Y9 will become L9, J10-Y10 and J11- L11.

Quick look at today now and 37573 returned to traffic as predicted on K4. 20127 did L13 10.59 Lynn - Peterborough and completed the turn. It either did K19 and took over L13 at Norwich (a fairly regular occurrence until recently) or came on at Lynn. K3, L12 and K19 turns were not seen. 20351 was on K17 but everything else was B9 operated. Timekeeping was very good.
