Think about it, you'd have to change the platform allocations, deal with any conflicts (service x can only use certain platforms, but theyll all be occupied), find a specific platform that is best suited and try to find a use for the staff that are sat around their waiting for the trains or subcontract it out.
Its not a simple thing which is probably why their trialing it. They've made great progress with the stock and service planning. A great innovation and I think the concept is great. Not an easy thing to do, their efforts should be commended!
I'm just being realistic that you shouldn't paint it as an easy thing to do, it seems quite complicated.
