# Assumption: $next_journey is a missed connection (i.e., if $journey had
# been on time it would have been an earlier train)
# * the wait time between arrival and departure is less than 70 minutes
# (up to 60 minutes to wait for the next train in an hourly connection
# + up to 10 minutes transfer time between platforms)
# * the delay between scheduled arrival at the interchange station and
# real departure of $next_journey (which is hopefully the same as the
# total delay at the destination of $next_journey) is more than 120
# minutes (-> 50% fare reduction) or it is more than 60 minutes and the
# single-journey delay is less than 60 minutes (-> 25% fare reduction)
# This ensures that $next_journey is only referenced if the missed
# connection makes a difference from a passenger rights point of view --
# if $journey itself is already 60 .. 119 minutes delayed and the
# delay with the connection to $next_journey is also 60 .. 119 minutes,
# including it is not worth the effort. Similarly, if $journey is already
# ≥120 minutes delayed, looking for connections and more delay is
# pointless.
