This is one of those occasions when you wish Emma Clarke was still in favour with TfL as the woman they use for the voice-over seems to be pitching at five year olds. Her over-pronunciation of certain words and the general speed of her voice (it seemed way too slow) drove me mad. Although maybe it is aimed at school children.
Thanks to Pedro for alerting me to the channel and if Tube Lines really want to embrace YouTube, perhaps we'll see videos added of dogs on skateboards going down Northern Line platforms or more escalator ski-ing at Angel. Or perhaps not.
