Something I find interesting is why is all the focus on Dover port queues? What is stopping some of the freight moving to the eurotunnel trains?
I'd also ask how many trucks currently travel overseas either empty or half full (half full including weights). I do wonder if some sort of consolidation centres near Dover and/or Calais could help with companies moving loads. If a company has 2 1/2 full trucks with 1 running Manchester to Paris and another Birmingham to Brussels, you could instead have 1 truck from Manchester, pick up the extra in Birmingham and then in Calais, split the load to go to the respective destinations. Reducing half or empty loads between the south east and Calais could ease the situation. Right now, the cost is there but it's more convenient sometimes to run the 2 half trucks as it speeds up the delivery. At least short term, if you can punish half/empty loads financially, it would mean only the full amounts are moving over here.
Moving to rail freight, of the goods which currently move by train through the tunnel, how much of that is moved by rail (longer distance using the 92s through the tunnel) or trucks (ferry or shuttle train). Is there much china clay, steel rail, aluminium ingots or bottled water going by trucks between Kent and Calais which could be moved onto trains? (goods taken from post #6).
Containers are good but I question do our ports have the capacity for a lot more containers? We know that Felixstowe right now is at capacity and with the excess possibly moving to other container ports, could they be close to capacity? I think the way for containers could be some sort of consolidation depot near Calais as well as near Dagenham or somewhere like that. Move the goods into containers, throw them on a shuttle train over to Calais and then they go from there however they want. I think longer distance container trains don't have much hope because of the loading gauges, paths and available wagons to move goods.
Even with rail freight, I think we need to think about the paths available. Especially paths to container seaports as paths are very hard to get, even with this slight reduction in passenger services, there isn't loads of space for more trains on the core routes.
