I think you’re being a bit melodramatic there, or are you just trying to be controversial on purpose?
I think we know that Tanger’s has had it’s problems but not all of them can be placed at the fault of it’s design.
I’d have to say Winchfield (not Woking, please if you’re going to single out incidents then please do some basic research before posting) and Wooton Bassett were down to the responsibility of those responsible of its operation and maintenance.
If your really that concerned about the performance of an original condition ‘Spam Can’ on a pres line rather than wait until 34023’s back in action why not have a look or get in touch with SLL or the Mid Hants and see how they’ve got on with 34070 recently to see how that’s coped recently? It’s hardly straight and level between Alton and Alresford is it?
