I like the fact the check-sum number was a 1 as well!

It has to be-Google the checksum as used by DB. There is an algorithm which is something like

1st digit x 1

2nd digit x 2

3rd digit x 1

4th digit x 2

5th digit x1

6th digit x 2

 

Add up all the INDIVIDUAL digits, then take the result away from the next whole multiple of 10.

 

e.g. for 101 101, the above is 1 + 0 +1 + 2 + 0 + 2 = 6.

Next whole multiple of 10 is 10, so 10 - 6 = 4, so checksum is 4.

 

So for 111 111 it is 1 + 2 + 1 + 2 + 1 + 2 = 9. Next whole multiple of 10 is again 10, 10 -9 = 1, so checksum for 111 111 = 1.

 

You have to sum the individual digits, so if there's an 8 in the number and it gets multiplied by 2, you sum up 1 + 6, not 16.

Another East Mids 222, the one with a coach number that happens to be the same as a newish steam engine, hence named Tornado.

Sheffield in autumn 2012.
