Jackson Sharp coaches

[Great Western]

About the seats facing backwards. We got to ride the White Pass train, (great experience!) and at the end of the line, the engine switched around to the other end. We all then stood up, and flipped the seats so they faced the other way! Don't know when someone came up with that idea, but it sure works.

These type of seats were very common on British tramcars/streetcars, which in the main were double deckers.

In my church we had a side chapel: the pews in the chapel were the same type for use when the chapel was being used or the other way when used as an overspill for the main church.

Walkover seats were/are very common on commuter trains.
