Most TPE services are bad for revenue collection; only a few Guards scan tickets (I've congratulated a few that do!) and many Guards do not even look at tickets, with a not insignificant number simply not seen at all throughout the journey.
Yep; a TPE Guard I know said today they have no intention of doing anything other than the bare minimum at the current time, and therefore tend to stay in the cab. They said if they were paid more, they may consider doing things differently.
Not quite.
Some operators (e.g. SWR) have non-commercial Guards, while others operate DOO services that have staff who do sell tickets but are not Guards (e.g. Scotrail ticket examiners, Southeastern on board managers, GTR on board supervisors etc).
The trains I find my tickets most frequently checked on are the Scotrail DOO services; their staff are really keen and I've even had my ticket checked as the doors have still been closing. I've made journeys to the Glasgow area consisting of several trains over hundreds of miles with no sign of any ticket checking staff up until I board the Scotrail ticket, then it can be checked within seconds of boarding!
But is it really an either/or choice? Are people choosing not to drink drive only because they think they are not going to get a ticket check if they go by train?
I suppose some people do odd things but this seems very obscure to me; do dozens of people really make such a choice?
Yes there are some exceptions. There are some Non Commercial Guards and there are some DOO trains with staff selling tickets onboard. Like the example that you mentioned of Scotrail and also the SE OBMs and the SN OBSs too.
What i find interesting is that the Ticket Examiners on Scotrail will very commonly walk through the train and check and sell tickets. But yet the On Board Supervisors on Southern who perform the exact same job rarely ever walk through the train and check tickets and seem to mostly just sit down between stops and go on their phone or read the paper. It is very rare that a SN OBS checks tickets from my experience and normally if you want to buy one you have to go find them. So it is quite interesting how different TOCs have different attitudes to ticket checking.
Generally these days ticket checking is very rare. Even when i travel on trains with Commercial Guards or OBS or OBM onboard i find that SWR and GWR and SE and SN are all appalling at checking tickets. The staff on these four operators very rarely bother to check tickets.
SWR is a very odd one as they have a mixture of Commercial Guards (who check and sell tickets) and Non Commercial Guards (who do not check and sell tickets) but both types of Guards operate many of the same routes. So one day your train may have a Commercial Guard onboard and another day your train may have a Non Commercial Guard onboard. I have taken the same trains between the same places and it often seems quite random which type of Guard you will get.
Eurostar and Merseyrail are the only other operators with Non Commercial Guards but unlike SWR all of the Guards on Eurostar and Merseyrail are Non Commercial Guards and do not check or sell tickets.
I believe that C2C used to also have some Non Commercial Guards on their 12 coach trains (which they called "Train Captains" instead) until around 2018 or 2019 i think. I think the London Overground had Non Commercial Guards too until around 2013 or 2014 i believe.
So to summarise the current situation is:
Avanti West Coast, Caledonian Sleeper, Cross Country, East Midlands Railways, Grand Central, Hull Trains, Island Line, London North Eastern Railway, London North Western Railway, Northern, Trans Pennine Express, Translink Northern Ireland Railways, Transport For Wales, West Midlands Railway, all have Commercial Guards who sell tickets on 100% of their trains.
Eurostar, Merseyrail, both have Non Commercial Guards who do not sell tickets on 100% of their trains.
South Western Railway, have Guards on 100% of their trains but it is a mixture of Commercial Guards who sell tickets and Non Commercial Guards who do not sell tickets.
C2C, Great Northern, Heathrow Express, London Overground, Stansted Express, TFL Rail, Thameslink, are all fully DOO on 100% of their trains with the Driver being the one and only staff member onboard.
Chiltern Railways have Commercial Guards who sell tickets onboard 100% of trains North of Banbury and are fully DOO onboard 100% of trains South of Banbury with the Driver being the one and only staff member onboard.
Gatwick Express are 100% DOO with nobody other than the Driver onboard South of Gatwick and with an On Board Supervisor onboard North of Gatwick who sell tickets (but they are not guaranteed and the train can run without them due to staff shortages).
Scotrail have Commercial Guards who sell tickets onboard all 153/156/158/170/MK3 trains. They are 100% DOO but with a Ticket Examiner onboard all 318/320/334 trains. The 380/385 are a mixture of the two above methods depending on the route. So there is always a staff member to buy a ticket from onboard.
Southern have Commercial Guards who sell tickets onboard all 171/313 operated trains and onboard all Clapham Junction to Milton Keynes Central trains and onboard some Redhill to Tonbridge trains. They are 100% DOO but with an On Board Supervisor onboard all Coastway and Mainline 377/387 trains who sell tickets (but they are not guaranteed and the train can run without them due to staff shortages). They are 100% DOO with nobody other than the Driver onboard all Metro 377/387 trains.
Southeastern have Commercial Guards who sell tickets onboard all Mainline 375/377/465/466 trains. They are 100% DOO with nobody other than the Driver onboard all Metro 375/376/377/465/466/707 trains. They are 100% DOO but with an On Board Manager onboard all 395 trains (who are guaranteed to be onboard).
Great Western Railway have Commercial Guards who sell tickets onboard all 150/158/MK3 trains. While the 165/166/387/800/802 are a mixture of some trains having Commercial Guards onboard who sell tickets and other trains being 100% DOO with nobody other than the Driver onboard depending on the route.
Greater Anglia are similar and also a mixture of some trains having Commercial Guards onboard who sell tickets and other trains being 100% DOO with nobody other than the Driver onboard depending on the route.
So yes it is very complicating but some DOO trains do have other staff onboard to purchase your ticket from.
