Network Rail invited me down to Whitstable in Kent to show me what goes on when a section of the railways is closed, and the team of orange descend onto the tracks to work non-stop to replace rails that are almost fifty years old. There's more on Network Rail's fleet of vehicles, including their RRV's (Road Rail Vehicles) here: https://www.networkrail.co.uk/running-the-railway/looking-after-the-railway/our-fleet-machines-and-vehicles/ My thanks to Chris from Network Rail for the invite and access. Thanks also to Daren Smith, a Construction Manaager also with Network Rail. Richard's channel (with his RRV Cab videos!) is here: https://www.youtube.com/channel/UCFwxArwmx5oRV2Btm8aU9zw Please Note: To see how I'm working during this strange times please read: https://geofftech.co.uk/safe.html
