After finally getting some positive news related to the death of her son, who was killed at a railway crossing two years ago on July 29, Sharon Jobson of Glencoe, received a shock this week.

CN Rail is suing her for $500,000 plus taxes and interest, for the cost of repairs it says it made to the track and the cost of traffic delays after her 22-year-old son John Jobson’s fatal crash.

A westbound Via train crushed his pickup truck and derailed with 116 people on board. Six people were injured.

The Transportation Safety Board ruled that at the time of Jobson's crash, the signs were not standard and were partially obscured and the train's horn wasn't retrofitted to modern standards.

Since that time, she has been lobbying for change at the rural rail crossing near Glencoe, wanting lights, gates and bells to prevent a similar tragedy.

Word came this month that $400,000 worth of upgrades are about to be installed, in large part because of Jobson's campaigning.

“We thought we had a peaceful ending to a tragic story for our family,” she says.

Now she’s calling a lawyer and preparing for a lengthy legal battle with CN.

CN has refused comment.
