Though delays persist, Metra will resume service on its Southwest and Heritage lines this afternoon.
The resumed service will allow commuters who traveled inbound this morning to return, thus avoiding the prospect they would be stranded in the city or be forced to find alternate transportation.
The Southwest Line will resume full service with the 2:40 p.m. train to Orland Park, followed by nine others. The first of three Heritage trains will resume at 4:50 p.m, according to updates on Metra's web site.
Metra had previously canceled all outbound train service due to the derailed freight train that was blocking Metra rail lines and leaking fluid into the Chicago River.
The last of four locomotives that derailed Thursday was put back on the tracks at 5 a.m., according to Chicago Breaking News. Officials are evaluating if there is any damage to the tracks as well as a bridge over the Chicago River that was struck by the trains.
Commuting delays will persist if damage is found.
