It makes sense for an early(ish) finishing 56 to be utilised when terminating at Park Lane anyway instead of having to have an extra bus out to do a short final trip on the 60.

Looking at the timings that seems to make sense, the 56 pulls into Park Lane 4 minutes before that 60 is due out, whereas the Drifter pulls in 6 minutes after the current 60 leaves. Also has the added benefit if it is a particularly busy run on the last bus of the night that nobody will be left behind, as well as getting the buses back to the depot ASAP.
