In a step towards improving the efficiency of train operation, Southern Railway commissioned the Intermediate Block Signalling (IBS) facility between Vadakara and Mahe (in the double line Electrified Railway section).
IBS, a signalling arrangement provided to improve the track usage (line capacity) in the railway sections(follows absolute block working), where distances between successive stations are more.
Introduction of IBS bifurcates 12.5 km lengthy block section between Vadakara and Mahe into two thereby increasing the line capacity. This will be helpful to avoid over detention of trains on both stations due to the non availability of line clearance from the station ahead. Passengers will be benefited by improved punctuality. Increase in line capacity will be helpful in dealing with more trains in the section.
Prior to the introduction of this facility, a train from Mahe to Vadakara was taking 10 minutes to clear the section if it is an Express train. In the case of Passenger and goods trains, it was 12 and 14 minutes respectively. After the introduction of the IBS facility in the section, if any train is waiting to proceed from Mahe to Vadakara or Vadakara to Mahe, the waiting time will be only five minutes if the preceding train is an Express train. If a passenger train or goods train is preceding, the waiting time will be 6 to 7 minutes.
IBS between Vadakara and Mahe is the seventh IBS facility in Palakkad Division. In Palakkad Division IBS facility is already introduced in Palakkad Junction – Parli, Parli -Lakkiti,, Payyannur – Charvattur, Kanhangad – Kottikulam, Kumbla – Manjeswaram, and Tikkoti-Vadakara sections.The IBS facility between Tikkotti and Vadakara Railway station was commissioned recently.
