I fail to see why the monorail is seen as at the end of its life? Its a very simple, electric powered design and if maintained well, the rolling stock should last far longer than a measly 33 years. The Diesel powered High Speed Train was built in the early 1970's and although they are being semi retired and on their second generation of engines, most are still in full operational service, doing sometimes thousands of miles a day up and down the country. It's likely there just isn't the will to spend any money on it. I doubt we'll ever get some new grand entrance either. The plan was probably to to put some crappy second hand land trains in the car park. I couldn't think of anything more tacky.
