A comment from David Tozer - many thanks for this info
Hi Keith,
Just seen the shot of the trio of 143’s. This train is regularly worked by three units. It all stems from over crowding issues with school children in the Torbay area which was shown of the local news months ago. I would suggest this is the only regular working of three sets of 143’s in service in the West Country. On reaching Exeter at least one is detached. I have seen a 150/2 and a pair of 143’s on this train. Dave
