I've completed the survey (although fairly cynical about whether it will result in any action). It is very frustrating to see the lack of provision for cycling when things could obviously be so much better.
A few years ago I used a local train in Denmark, on the way to take part in the Vatternrundan event in Sweden. Middle carriage had a wide platform level entry, and one side of the compartment was left open so that it could be used for bikes, wheelchairs, pushchairs. I was towing a two wheel trailer with my tent and camping gear, no problem getting on the train. On the way back there was a replacement bus service for part of the route. Again, no problem as the driver helped me get the bike and trailer into the luggage compartment on the coach. Such a contrast with what happens here.
