"The traffic on the affected Up line was restored at around 8.15 am, after around eight hours of efforts. During the restoration work, mail express trains were diverted on the Mid line. So, the Up and Down lines traffic was running on Down and Mid lines," he said. He further said that due to availability of only two lines as against the usual three, trains moving towards Mumbai from Pune, and also due to the movement of ghat banking locomotives, few Down trains suffered detention of up to one hour during the restoration work.
