Yes I understand that however the route was changed during the pandemic -- the 17 use to drive past The Crescent not go round it, it did in the evening however but thats not the point, the route was changed by the backdoor (nothing was stated on their website that this was happening), most people I spoke to in the area still thought at the time the bus was still going to be quick into town but seemed baffled by the route as it is now. You say the E stands for evening route other people have said otherwise so what is it then? So why not just have the 17 just be 17 than adding a random letter to it?
Why not just keep at as 15/17 or if its just terminating in city centre just have A?, mind you they did this with the 15s not long ago 15a (anticlockwise) 15c (clockwise) but yet St Marys is 1A via one route and 1B the other route...
So the "reprogram" just reboots (like a PC/phone)? I wouldn't be surprised then that the display needs replaced.
If you go back to Page 11 of this thread I have been told as an example with NXWM (company that owns Xplore), they use E for Exception and works as Part Route -- E for Evening up here has to be one of the stupidest things I have ever heard (nothing against you), as I thought that too but why have E on the 17 and not on the other services? (so if we went with that theory it was "part route" but it isn't it runs through mostly with no exceptions, I think someone at Xplore needs to look up a manual on when to use letters and what they are for than throwing them on buses, I maybe a bus spotter but far from an expert here either) 9/10s have A's in the evenings (so where is the E for those then?), why not apply it to all their services? As I say I just think my route I use is always used as an experiment as over the years they have altered the route that much its got a history of changes... a la 15A/C (again A isn't anticlockwise is it for St Marys and the B is for what?)
