Tasmanian train drivers are posting dashcam footage of near misses onto Facebook in a bid to stop motorists trying to beat trains at level crossings.

Over last weekend alone drivers reported six near misses in the north and north-west of the state.

The train drivers said the motorists did not stop at the crossings and ignored warning horns, bells and signage.

The video clips showed cars crossing the tracks under the noses of the trains.

One driver appealed to the public on Facebook: "Don't be in a rush to get to the other side. Lose a minute, not your life."

Damien White from TasRail said one incident in the state's north mirrored a previous deadly crash.

"The one near Longford was almost a carbon copy of an incident two years ago where there was a fatality," he said.

Acting Inspector Luke Manhood warned motorists the risk was not worth taking.

"They're taking a huge risk, there's nothing the train drivers can do to avoid a collision," he said.

Footage handed to police to pursue offenders. He said the footage could lead to prosecutions if it helped police identify offending motorists who faced fines, court and the loss of demerit points.

"They forward that footage through to police and these incidents are investigated, and where we can identify the people responsible we do prosecute them," Acting Inspector Manhood said.

"The most significant penalty is that they're going to die. It really is that serious."

Mr White said TasRail planned to roll out six fixed cameras at level crossings within months.

"We know where some of the hotspots are, both in terms of poor behaviour and certainly some of those locations where you know out in the country where car speed is higher," he said.

Many level crossings in Tasmania do not have boom gates and some do not have bells or flashing lights, meaning it is up to motorists to treat the crossing as a stop sign.

While Tasmania Police said extra infrastructure at level crossings could be considered, TasRail said the state's low train and road traffic levels meant there was no need to install boom gates at crossings.

Deputy Premier Jeremy Rockliff said he would look at the footage.

"I'm alarmed at the fact that people have not got that message yet but we must be forever vigilant in making sure we have got that message through."
