"Every single death or injury on the railway network is avoidable if people approaching it actively recognise the hazards that exist and obey the warning signs and signals," said Mr Quinn.
Cairns also urged people to avoid using using mobile devices at crossings which could distract attention.
"Trains, especially passenger trains, are very quiet and when people have the added distraction of either music in their ears, or someone speaking to them on a cell phone, then the risk of being hit by a train increases," he said.
The safety message was just as valid for motorists, said AA spokesperson Dylan Thomsen.
About half of the country's 1400 level crossings have some electronic warning systems such as flashing lights, bells or barrier arms but there are still about 26 crashes a year between cars and trains.
In the first half of this year there have been seven crashes between cars and trains, which was fewer than unusual.
But there had been 86 reported near collisions, showing "there are still far too many people taking huge risks", said Mr Thomsen.
"Crashes between cars and trains usually involved a driver either not seeing the train or trying to beat one across the tracks, and people needed to look carefully at crossings and be more patient," he said.
Rail Safety Week events will be held in Auckland, New Plymouth, Mt Maunganui, Tauranga, Levin, Greymouth, Westport and Ashburton.
