Via Rail customers travelling between Toronto and Ottawa can expect delays of several hours after a freight train derailment near Smiths Falls, Ont., blocked the tracks Wednesday, the company says.

Via said the Canadian Pacific derailment happened Wednesday afternoon and is not expected to be cleared until Thursday morning. Via had previously said the derailment occurred near Brockville, Ont.

Via has arranged bus travel for people affected by the accident but said passengers can expect delays of two to three hours.

Passengers choosing not to travel may opt for a full refund or change of reservation at no additional cost, the company said.
