I've sometimes wondered why modern tramcar makers don't make double
deckers. Yes, modern artics swallow lots of people quickly but they also
take up a lot of space. A double deck artic (with connections at both

That's an engineering detail (he said having no idea what the answer is!).

Not insoluble but possibly expensive.
