One by One They Go

One by one they go
Stop go stop go
Blow the whistle
Move the cars
Speeding through
Seemingly endless tunnels
With frequent stops.
But then
When you think you're
Doomed to travel through
Endless
Seemingly endless tunnels
Light breaks through.
One by one they go
Move the cars
Get back on time
Plunging through never ending
Seemingly endless tunnels
Stop go stop go stop go
Long enough
Time to read
To write
To think
To sleeep
But not completely endless
There's the stop go stop go
And one of the stops
It's time to go
To leave the cars
Before they return
To seemingly endless
Stop go stop go stop go.
