The 67-year-old rocker still enjoys the same hobbies he did as a youngster, but sometimes his love of train sets irritates his wife, model Penny Lancaster, who tells him to stop playing station controller and speak to her. Rod - who has appeared in specialist magazine, Model Railroader - said: "I go upstairs every day and play with my trains. If I`ve been up there too long Penny will call up and say, `Darling! Time to come down!` " Playing with his trains is a far cry from his hedonistic youth, but Rod - who has eight children - believes it was his love of sport on a weekend that stopped him ever going too far with drugs. He told The Sun newspaper: "It was a different time when I started doing cocaine. It was an elite club here in Hollywood, made up of very famous actors and actresses. "In those days it was pharmaceutical coke. You didn`t have to stay awake. It didn`t ruin your sex life. You didn`t have nosebleeds. There was no big hangover and you just did a tiny bit. "But I was never a druggie. I`ve never actually bought any in my life. I didn`t go to rehab and it didn`t interfere with my relationships or my kids. And that`s because of football, that`s all it was."
