Robert .Whenou talk about the Semi's at Tamworth,they were a Magnificent Machine thundering up the main lines.But to see a Streak come down the hill through Grantham Station with the Chimes blowing at 70-80 Mph was another thing.Used to do the trip to Grantham about every 2-3 weeks in the early 50s aged 14 from Lea Village.Wasntit different in them days ,parents never worried so much.Wouldnt let my children do it now .
