Where do you prefer to sit on the bus?

@NankerPhelge we have double decker trains in Metro Sydney.

@SW-User Really? How the hell do they get through tunnels?

@NankerPhelge Sydney is known for its tunnels. They got in tunnels. The train line from Sydney airport to Sydney CBD is tunnel all the way.

@SW-User I mean how does it fit in the tunnel without enough headroom? I've seen the ends of railway tunnels and I only know of one that might have enough room for a double decker train to pass through, and even that is debatable.

@NankerPhelge it fits.

@SW-User It's not as high as I expected. I was expecting it to be the height of a double decker bus. That looks about the height of a double decker Lotus Europa. Lol :)

@NankerPhelge they are double the height of our Melbourne metro trains. That's what ours look like.

@SW-User That looks like the average train in the UK these days. They are not as nice looking as the ones we had in the 60s and 70s. Here is one I travelled on myself in 1967 and again in 1970:
