I've recently started commuting between Tonbridge and London St. Pancras, changing at London Bridge on to a Thameslink service. I use Southeastern's ITSO smartcard loaded with a walk-up railcard-discounted daily fare from a TVM.
Whilst this worked well previously with a commute in to London Bridge/Z-16, since switching to St. Pancras i've experienced a significant number of gateline rejections entering St. Pancras in the evening. Typically, the rejection code is 57 (PPT INVLD: Location not covered by PPT, barcode: NLC not valid), but sometimes I am also receiving 12 (TIME O DAY: Not valid at this time). Rarely, I have also received rejections when exiting in the morning.
I am somewhat puzzled as to why this is happening. Rejections seem to be more common if I use an Off-Peak ticket, but I do also sometimes receive it with an Anytime ticket. The error 12 rejection is especially puzzling - I was definitely using an Off-Peak Day Return ticket at that time, but the TON to STP Off-Peak Day Return ticket carries a restriction of BC - which only applies restrictions prior to 09:06. It feels that the barriers may be processing the validity incorrectly but I have no way of checking this beyond observing whatever codes they throw up. If anyone could shed some light on this i'd greatly appreciate the insight!
Luckily, gateline staff have waved me through each time this has happened so far. However, i'm concerned that my luck will eventually run out and that I will be denied entry despite holding a valid fare.
