I was in the South London area yesterday (8th of the 7th) and caught sight of a direct rail class 47 comming up fro SL, it had a name but was too far to make out and I missed the number, and today I saw a class 66 in Colas livery passing through Wandsworth Roed that I swear was numbered 66 746 but I cant find that in any book. Can anybody shed any light on either of my two problems. Thanks.
