Engine 70414

I grew up listening to train engine 70414,
Was using steam keeping it clean and green,
It was going on ten maybe fifteen miles an hour,
It went slow although it had the raw power,
But those days speed did not count very much,
Quality counted more, 70414 had a soft touch,
Then came the fifties and the old engine retired,
He was still going well but its heart expired,
Nowadays speed counts more than quality, sadly,
So 70414 has gone to retirement and done so gladly,
