HS2 may be the most exciting news in the world of Railways, but by the time it's built the existing system may well have to cope with twice the number of passengers it does today. The team will look at the many measurers engineers are taking to ensure our ageing rail system stays on track. Liz Bonnin looks at how signals may disappear from the tack side and how hearing impairment could be one of the biggest killers on the railway lines. Whilst Maggie Philbin looks at how a train traveling at 125 mph is set to revolutionise track side maintenance.

Bang Goes The Theory can be seen on BBC One and BBC Two (Wales only) on Monday 28th April 2014 at 7.30pm. Full schedule and iPlayer links are on bbc.co.uk. Read more about the current series.
