After watching The Railway 24/7 episode 3 one of the RPIs confronted a passenger without a ticket he asked if the passenger could have bought a ticket online.
It brings an interesting question. If there is a broken TVM / no ticket office / no PtP machine and the guard remained in their cab is the onus on the passenger to buy a ticket on line. I don't believe it is since the passenger isn't expected to be proactive to buy a ticket but to buy one when reasonably possible (not having to seek the guard out or delay their journey when changing trains to buy a ticket). But I wonder if there are any cases or guidelines to back this up
