> a fourth one replaced by a voucher for a 450km taxi ride

When can I move to Germany ?

In the UK if your train gets cancelled its either:

    1. "Tough shit. Suck it up buttercup"
    2. The infamous Rail Replacement Bus Service

Most of the time option two doesn't even get offered.

So yeah, you would not find me complaining if the train company offered me a taxi voucher if my train was cancelled !
