Banff Alberta - The remaining rail car from last December's train derailment near the Banff townsite has been removed from Forty Mile Creek.
 
Crews have been working at the cleanup site as part of the latest phase of the operation, including into the night under powerful lights.
 
The rail car was removed about two weeks ago.
 
"The remaining rail car has now been removed from the site along with the small amount of grain and fly ash which remained in the creek following the incident," wrote Salem Woodrow, a spokesperson for Canadian Pacific Railway, in an email.
 
"We've removed the majority of the sediment. The material will go to an approved landfill."
 
CP would not say which landfill.
 
"It is an approved landfill. The name of it is irrelevant," Woodrow wrote in an email.
 
On 26 Dec 2014, 15 Canadian Pacific cars left the tracks while crossing a bridge over 40 Mile Creek, with eight falling into the creek.
 
The cars contained soybeans, lentils, and fly ash, a fine grey powder byproduct from the combustion of coal.
 
One rail car, which contained soybeans, was purposely left in the creek and used as a temporary dam to facilitate the work.
 
The water from the creek was diverted and remediation experts isolated the work zone with dams to remove the rail car and contents from the creek.
 
Water removed from the work zone will be run through a water treatment device to ensure that potential contaminates have been removed.
 
Electric fences were installed away from the site to keep wildlife away.
 
Woodrow said CP originally estimated about three weeks for the cleanup, but that was dependent on weather.
 
"We are not quite finished our remediation plan yet," she said.
 
Woodrow said she has no information on the cost of the cleanup operation at this point.
 
The Transportation Safety Board continues its investigation into the Banff derailment.
