The train operators do not like allowing cycles on their trains. The carriages are made for passengers. The luggage wagon no longer exists so these spikey awkward machines have to be boarded alongside passengers who are averse to being bumped, possibly bruised or otherwise inconvenienced by our bicycles. It seems the surest tactic to avoid being discriminated against on account of our bicycles is to use a proper light weight folder such as the Brompton. In its transit case this very capable bike is no more than another piece of luggage on the bag shelves or on the luggage rack.
