I'm glad you both enjoyed my find.
I see these videos and I feel a bit of joy seeing the mix of power and then the renaissance of service with the introduction of HSTs and DMUs on the lines during the 1980s. It was in the mid-1980s that I visited Britain with friends and then with my grandmother. It was with her that I had the opportunity to sample a bit of the Southern Region as we took a trip to Hastings then over to East Bourne on a day out to the coast, and then a bit of the Midlands when we took a trip up to Liverpool to search church records for her grand mother.
The service then was and still is far above what we have here in the US, yet so much was lost too, and sadly the Great Central succumbed I think too soon. With the burgeoning populace now taking trains, they are all squeezed into much tighter corridors rather than having the luxury of multiple lines. I would think that the officials, after cutting this line in the name of profits then all without thinking about the future, must be kicking themselves in the backside as they are now facing capacity problems. The sad part is once a line is gone, it's usually gone for good not because nature takes over but more due to the cost of bringing it back. In many ways you have been lucky across the pond with the initiative to return many lines to operation, sadly it's not the case here.
