CS, thoughts:

The little girl, her first ride in a train,
bent over the window and clapped in joy;
the mother, as is her wont, pulled her back.  (as her wont, seems tell to
me)

A pensive wife, forced to maternity leave,
waved timidly to her man, as he looked
at the slow movement of platform clock. (the platform)

A student was anxious, repeatedly looked
at the papers; the certificates he hoped (his papers)(no the)
were worth their weight to secure him a job.

An old man was wheeled to the compartment, (prosey, but do take out some
said)
he had a broken hip- some said he broke his
bone first and then had the nasty fall.

The door of the bogie got jammed and (no got or and)
the wheelchair got stuck. The guard
blew his whistle and porter was worried; (no and and cap Porter)
the jerk might induce another fall. (cut, it does not seem to fit)

With effort the huge load jerked ahead (cut huge)
emitting some puffs of black smoke.
The crows on a pole fluttered for a while (cut The and for a while/but
settle down again)
but settled down again- crowing inwardly:
the engine moves in one direction always.

The old man managed to jump inside as
the wheelchair dropped on the platform.
The crowd heaved a sigh of relief,
even as another bone cracked in his arm.

Bemused, I strolled to the next platform. (Bemused seems the wrong
impression for a broken arm.)

Good luck.
