yes, or just nick them and throw them out the window....
My first memory of train travel involved a Saturday trip on the non-corridor EMUs on the MSJ&A route into Manchester.
The train arrived at Oxford Road minus all its light bulbs, which had been ejected (with some force) in the Old Trafford tunnel.
Such was the esteem people had for BR and public property in those days.
While regions other than WR and SR had 3-a-side seating on long-distance trains, all the local trains were 6-a-side in compartments.
Compartments were also marked Smoking, Non-Smoking and Ladies, to further restrict usage.
I think we are well rid of them.
It took longer to rid the network of trains with multiple slam doors to a carriage, with the arrival of power doors and the "PEP" design.
I think the 310/312 design was the last of that type.
Some DB ICEs have a few "compartments" within the open plan with half-height glass surrounds which can be booked, eg for families or business meetings.
And sometimes with great views out front over the driver's shoulder...
TGVs have some special areas too.
