[only quoting the last half of Kipling's poem 'The King'] since it mentions nostalgia for the past AND trains =

"Good-bye, Romance!" the Skipper said;
"He vanished with the coal we burn;
Our dial marks full steam ahead,
Our speed is timed to half a turn.
Sure as the ferried barge we ply
'Twixt port and port. Romance, good-bye!"

"Romance!" the season-tickets mourn,
"~He~ never ran to catch his train,
But passed with coach and guard and horn --
And left the local -- late again!"
Confound Romance! . . . And all unseen
Romance brought up the nine-fifteen.

His hand was on the lever laid,
His oil-can soothed the worrying cranks,
His whistle waked the snowbound grade,
His fog-horn cut the reeking Banks;
By dock and deep and mine and mill
The Boy-god reckless laboured still!

Robed, crowned and throned, he wove his spell,
Where heart-blood beat or hearth-smoke curled,
With unconsidered miracle,
Hedged in a backward-gazing world;
Then taught his chosen bard to say:
"Our King was with us -- yesterday!"
