Milepost 87.0 Laggan Sub - The Transportation Safety Board of Canada (TSB) is investigating following a train derailment between Banff and Field on Thursday.
 
The government agency said no injuries were reported.
 
The TSB said it was notified of the incident at 20:20.
 
Chris Krepski, a spokesperson for the government agency, told Global News that 20 cars derailed at Mile 87 at the Laggan Subdivision.
 
According to initial reports, 10 of the cars that derailed were empty while the other 10 cars were loaded with grain, the TSB said.
 
The agency confirmed no dangerous goods were involved.
 
The TSB said the site of the derailment was difficult to access and so it was gathering information remotely.
 
A determination has yet to be made whether its investigators will be sent to the site, the agency said.
 
Typically, the railway involved is responsible for clearing the tracks and the accident site, the TSB said.
 
The incident was reported to the TSB by Canadian Pacific Railway (CP).
 
When contacted about the derailment, a representative with the Teamsters union that represents some Canadian rail workers told Global News of a close call near Field on Wednesday night.
 
The union said a locomotive engineer had to use emergency brakes because the regular air brakes didn't function properly.
 
The TSB confirmed it was investigating an "occurrence" on Wednesday night but did not elaborate.
