Its cheaper to bore one tunnel these days.

It's always been cheaper.

But two tunnels gives you an escape route via cross passages. It help
prevent collisions. It takes away the drag from passing trains.

And BTW you can profile them differently for acceleration...


Isn't that how this argument started ...?

No. It started when I said a single large tunnel is cheaper than two
small ones.

And we are coming to realise it may very well not be.

But then its usual to find that whatever you say, the converse is true.

Well so far there has been no evidence of what you say.


Rather like listening to a Labour party person.

In your case yes, is your alter ego going to say "a scab is a SCAB"?


Cheaper may not mean better it depends on the requirements.

Well, a comma is cheap, and would have made your inane truism at least
grammatically correct.

Here's one, for you to use.
