The intent is not to add any new services on the existing freight lines to deteriorate the system. The current system might remain a bit the same, which has concerns, but the incremental services or the incremental passengers would be on dedicated tracks not affecting the freight trains.
We all went through a crisis over the last two years on the supply side in terms of shipping and the train industry. We know how sensitive it is. Keeping the reliability of freight trains is important. We don't want to increase the burden on CN, CP and other operators.
