This is probably true but the unguided section at Orchard Park
probably and the approach section to Cambridge North station
definitely are unguided on cost grounds.

Comparing to clearing the ground, casting the concrete and moving into
place, how much extra in percentage terms would bolting a pair of
steel guiderails into place cost? It can't be that great and I'd be
surprised if they didn't recycle the old rail track to create them.

I suggest you come to Cambridge and have a closer look at Guided Busway
construction. You wouldn't then spout that nonsense.

What nonsense? Are you saying guideway rails are made of some special type
of highly expensive Unobtainium and the steel from recycled rails just
isn't up to the job? Its a ****ing busway, not a railgun launch platform!
Its primitive construction personified - it doesn't even require points
FFS.

They're not rails. And there is no guideway at junctions either. I'm afraid
you are talking out of your posterior. They aren't rails for starters.

Which has other benefits, such as not being restricted to
buses-with-guide-wheels.

Not so. The steel guide rails at the entrance and exit to the roadway
prevent anything other than guided buses from entering. There's a similar
arrangement controlling access from the guideway across Harrison Way at
St Ives.

I'm pretty sure plenty of bus drivers with good judgement could get an
unguided bus between those rails.

Not safely which is why it's verboten.

Still, perhaps like in Edinburgh, sense might one day prevail and the
whole pathetic system is ripped up and replaced by a tramway. And don't
say there isn't the room - if they can squeeze a tramway into hilly
nottinghams market square and weave one around the centre of manchester
they could do it in cambridge too.

There I agree with you, though I think heavy rail would have been the better
solution for St Ives.
