Stop and start and stop and what's this driver on?

If taking the train takes less of a strain then why am I feeling so stressed?

91021
and I've been in here before
but with carriages all looking alike
it's likely that I'm wrong.

Moving on at a brisker pace
to face the coming day
and it's no use me running away
I'll only end up where I began.

Tuesday as it should be
said someone rather dolefully
I doubt it was me
but
you never know.
