I'm driving up to Taunton Saturday morning, leaving car at Premier Inn hotel, then walking the short way to Taunton train station to get the 7:28 train. Gets me in Paddington at 9:29. Get train back to Taunton at 17:04, and spend a night in Taunton premier Inn. Cost of hotel £35, and train return £54. Great deal, and avoids the rail works.
