Very much so. I wish train drivers and guards could have grilled them rather than uneducated (on this matter) MPs - they wouldn't have got away with deflection and we could have pinned them down. The importance of having a guard safely dispatch a train has barely been mentioned.
I'm not sure it matters when the other side are repeatedly unable to answer why DOO operates elsewhere and no one has been shouting "UNSAFE" from the rooftops anytime previously. The union repeatedly failed to put that right today when given the opportunity. Piss poor.
