Database issue ? Diagramming (schedules) issue ?
We often have PIS code issues and they can be traced back to the wrong codes being printed on our diagrams or left hand not knowing what the right hand is doing in terms of calling patterns etc.
I've lost track of the number of PIS codes not matching what my diagram states. Is that potentially what's happening with 700's ?
As to the used to units thing. Any tips ?
I've not had the wrong PIS code since working on TL though we can't get our codes to work on Southern stock when we do the Brighton - London Bridge services. In fact the codes often don't work on the Electrostars either on that route but never had a problem elsewhere.
Today's diagram saw me working 700104 and 700108 from 3 of the four cabs. I had PIS faults showing on the HMI all three times though I *think* the announcements were still being made on two of them (it doesn't make the announcement in the cab like it does with Electrostars). I managed to manually re programme the third by working out how to enter a code direct in to the PIS (you normally set it up on the driver interface, hence no-one has a clue how to use the actual PIS hardware).
It seems just like Electrostars, the 700s don't like platform 3 at East Croydon. Where that just gives a GPS location fault on an Electrostar it seems to totally confuse the 700 and it just defaulted to it's "No Journey" setting til I got it running again. Now I think I know how to do it, if it goes down again I will do the same hopefully...

I should add though that it also happens on Northbound services and on Southbound services north of the river so it's not just East Croydon that gives me grief
It's this PIS fault which I *think* makes (
maybe, contributes) the first four coaches only release doors and so the driver has to do a manual override at each station hence slowing everything down. Also some drivers are more familiar with how to do this than others so delays will be different...
This manual override is different to the override done at TL core station if a stopping point is missed. Hence the confusion and difficulties for some.
