Railway harmony

I used to be a watchman on the permanent way

Watching out for intercity 125s barking round the curve into the Manton junction, whilst the crucible welders stacked their pots of magnesium and sinter over the one mile continuous track

My watch was to warn the late night spit that a 1000 tonnes of 100 mile an hour passenger tube was on the opposite way

And, similar conjunction replacing fishplates and pandrols, this years later on summer night with rain just finished I remember that curve of rail under the road bridge at 3am
