What are the differences in the seating layout in the XC sets? Have to say I thought they were all the same as all the carriages have been stripped out and fitted with new interiors.
As you say, there are other differences based on the coaches' origins: loco-hauled conversions have CDL panels on the opposite side to HST-built stock, and the aircon external roof vents are different too (three small ones as opposed to one larger square one in the middle).
In your view, how much better is this than the Farish set? I've got the Farish one and am debating whether to get the Dapol one too. Other option is the EMT one, but I'm slightly reluctant there as the coaches in the set don't match the extra ones available (branding is missing from the set ones). Yes, I know it's a fairly simply thing to fix, but with models costing this much it shouldn't be necessary!
And a question for Dave - when can we expect the Grand Central and WSMR buffets to appear? When they arrive (plus extra TFO for WSMR) that will be those sets completed!
