Would A Tram-Tube Be Feasible?

I have seen tram-trains at work in Karlruhe, Kassel and Mulhouse and they work well as they travel on the tram-tracks in the city centre and the train tracks as they travel outside and to the next major town. We’re soon to introduce Class 399 tram-trains between Sheffield and Rotherham as an experiment and after what I’ve seen in Europe, I don’t believe that the trial will be a substantial failure because of the concept.

When I looked at Crossrail 2 at Wimbledon, I said I had a bonkers idea. If we can have tram-trains, then why can’t we have tram-tubes?

Dimensional restrictions would apply and I suspect it would only be possible with the larger size of tube train. But the cross-section of the modern S7/8 stock is not that different to your average tram, although they are longer. Although, I’ve seen some substantial tram-trains in Europe, with at least four coaches.

What gave me the thought was the problem of the Tramlink platforms at Wimbledon would be solved if they could run up the District Line to another terminus.

It is probably infeasible at Wimbledon for various reasons, but once the tram-train technology is proven in a UK environment, I can’t see why the concept might not work in the right way in the right place on the sub-surface lines of the London Underground. One possibility would be to create a branch line shuttle. Such a concept could have been used at Barking Riverside, but they have decided to extend the Gospel Oak to Barking Line instead.

I do think it will be wrong to underestimate the devious minds of those engineers trying to squeeze the last drop out of London’s transport infrastructure.
