The TfL website says:
Cross River Tram is a proposal for a tram service running on-street between Euston and Waterloo, with branches to Camden Town and King's Cross in the north, and Brixton and Peckham in the south.
If you're fed up with travelling on some of the most crowded stretches of the Northern, Piccadilly and Victoria lines, you'll be able to take the tram instead. It will also help out those of you who don't feel well-connected - by rail or Tube that is.
Or maybe not. Supporters of the scheme such as Labour AM Valerie Shawcross fear that Mayor Johnson will dump the scheme as one of the "tough choices" he's planning to make about transport funding in the capital. Remarks he made during last week's feisty defence of his fares hike - reported here - have deepened their pessimism.
Shawcross also happens to chair the Assembly's transport committee, which meets tomorrow morning at 10.00. The agenda includes a seminar about the project. Watch the webcast for some lively live action. The immediate mission for the tram's fans is simply to stop The Blond booting their baby into the long grass.
