That aside, when arriving at a bus stop or station. surely it will be easier to glance at an RTI sign than to fumble for a phone in a handbag, open the app, select the bus stop etc etc.
Have the ones used on the for Rail fixed the omission that exists on the standard bus RTI signs ( IMHO) of not actually displaying the current time??
The sign at Wingate does not display the time.
On the Auckland RTI thread there is some interesting discussion comparing GPS and track circuit based systems. In much of Wellington there will be no choice but to use a GPS system. I can imagine the following scenario at Petone:
RTI sign says that next train to Wellington (train A), stopping at Ngauranga and Kaiwharawhara, will arrive in two minutes.
After four minutes a non-stop train races past. Train A will still arrive in two minutes.
After another four minutes the sign says that a train that does not stop at Ngauranga or Kaiwharawhara is due. That train duly arrives and departs. Train A is still two minutes away.
After two minutes a Wairarapa service to Wellington jumps to the top of the list and arrives and departs.
Two minutes later Train A finally arrives.
Perhaps it is not an issue because regulars will understand what is going on and I am sure that station staff will keep passengers updated.
