I am no longer as agile as I once was. (I should probably invest some time and energy in flexibility exercises.) Consequently, I had booked a lower berth sleeper ticket. I boarded the train relatively early and proceeded to get ready for bed as the compartment was quite small, and doubtless be even smaller once the possible compartment mate showed up. In the event, he only appeared shortly before the train pulled out and then only to sign some piece of paper and to announce he had secured another compartment and therefore I had mine myself.
The train left the station in one direction and proceeded in for unknown time like this as I sought the best position under the duvet. It came to a long stop possibly to divide the train into Glasgow and Edinburgh sections. My section started moving in the other direction than it had.
I fell into a relatively fitful sleep. In the midst of a particularly strange dream which featured a knocking radiator, I was awoken by the train "host" (i.e. porter) who informed me we were an hour out of Glasgow and gave me my coffee and shortbread.
I dressed for biking and packed my panniers, taking great care to search the compartment for any misplaced items. The last time I took a sleeper to Glasgow, I lost my hat.
