Banff Alberta - Conservation advocates and experts are concerned a proposal for a Calgary-to-Banff passenger train is chugging along without addressing some key environmental issues in and around the national park.
 
Liricon Capital Inc., the lead private sector proponent, is touting it as a hydrogen-powered transportation solution with lower greenhouse gas emissions than driving.
 
The company says it has received support from municipalities and the tourism industry, but the Alberta government has told the Globe and Mail it won't invest in the $1.5 billion train as it stands because the financial risks are too high.
 
Environmental organizations, including Canadian Parks and Wilderness Society, Yellowstone to Yukon and Bow Valley Naturalists, and some scientists say the proposal also has environmental risks.
 
"This is one of the most important conservation landscapes in North America. It also happens to be one of the busiest in terms of transportation infrastructure. The thought of this new rail line, which would be really close to the existing rail line, is really troublesome, not just in the park, but outside the park on provincial lands and Stoney Nakoda (First Nations) as well," Tony Clevenger, a senior wildlife research scientist with the Western Transportation Institute at Montana State University, said from Banff.
 
Concerns include wildlife deaths along the rail line, particularly grizzly bears, which have been hit and killed on the existing track, and the fragmentation of wildlife habitat in Alberta's already busy Bow Valley.
 
Josh Welsh, Alberta program manager for Yellowstone to Yukon, said passenger rail to Banff isn't a bad idea.
 
"We see it as a means to potentially provide a sustainable transportation vision that could work for wildlife, people, and the planet," he said.
 
But, he added, there's not enough information or collaboration to know whether it works for wildlife.
 
"The Bow Valley is already being squeezed by development."
 
A recent report by the Canmore-based organization found the mountain town's footprint has grown five times in 50 years.
 
It focused on grizzly bears because "if you take care of grizzlies, you take care of a lot of other things."
 
Another report by scientists, published this spring in the journal Movement Ecology, found bears have lost about 85 percent of their original habitat in the Bow Valley.
 
"So, when you talk about another piece of linear infrastructure, which a train line is, we are talking about cutting up the habitat, disconnecting wildlife," he said.
 
Devon Earl, conservation specialist with Alberta Wilderness Association, said the Calgary-based organization has similar concerns.
 
"We don't think there has been adequate assessment of how wildlife will be impacted," she said.
 
She also questions whether a train would actually reduce cars on the highway, saying bus service may be more cost-effective.
 
Liricon has said Parks Canada needs to consider raising the entry fee to Banff National Park for private passenger vehicles and expanding bus and shuttle service between park attractions.
 
Parks Canada said in a statement that its first priority is to protect the ecological integrity in national parks, but it's "not currently reviewing a proposal for passenger rail in Banff National Park."
 
Any review, it added, would look at policy and legislation, including the Impact Assessment Act and park priorities.
 
Jan Watrous, managing partner with Liricon, said a study shows the train could carry about 11 million passengers annually and reduce highway traffic.
 
"The fact that the passenger train will be a zero-emission hydrogen train and significantly reduce vehicle traffic, means human and wildlife mortality on the highways will be dramatically reduced. The specifics of the hydrogen solution and wildlife mitigations will be determined through consultation," she said.
 
The company has said it's considering using technology such as lighting or sound to warn animals about approaching trains and reduce wildlife deaths on the tracks.
 
Colleen Cassady St. Clair, a biologist with the University of Alberta, said she spoke to Liricon about that idea, which came out of some research she led.
 
Although early tests show it can be effective for some wildlife, she said "there's a lot of untested terrain in a warning based system."
 
St. Clair said there could also be challenges with wildlife crossing structures that go over or under the tracks.
 
Clevenger, who specializes in wildlife crossings, said he's heard the company was looking at underpasses to align with those under the Trans-Canada Highway in Banff National Park.
 
"That's very simplistic and completely unfeasible. You can't put in an underpass on the new rail line without putting an underpass on the Canadian Pacific Railway main line. You'd have to do both," he said.
 
Clevenger said the measure would reduce already compromised wildlife habitat.
 
A passenger train, he added, could end up increasing overall traffic to the national park.
 
"It's a landscape that is just overflowing with people. I don't think they can manage it," he said.
