There could be some delays at VIA crossings next week as the rail company and the city perform data collection work.
The affected crossings include at Merivale, Woodroffe, Fallowfield, Greenbank, Jockvale, Strandherd and the Transitway.
Part of the work will include activating the lights and barriers.
This will be done between 10AM and 3PM Tuesday to Thursday
VIA says its train schedule will not be affected and that noise is not expected to be an issue.
