Kolkata Metro’s shortage of 121 running staff has forced the Railway Board to look beyond the network’s own cadre, revealing how service expansion can outpace the workforce needed to operate an urban rail system safely and reliably. The Board has directed Eastern Railway and South Eastern Railway to arrange crew for Kolkata Metro, while asking the Metro to seek staff from other railway zones and examine outsourcing or redeployment options.
The immediate issue is numerical. Against a sanctioned strength of 427 running staff, Kolkata Metro has 306 personnel on roll, leaving a vacancy of 121, or 28.34 per cent, according to a Railway Board letter dated September 3. Running staff include motormen, who operate Metro trains, and shunters, who assist in train-yard operations. In the broader railway system, these roles correspond to loco pilots and assistant loco pilots.
The figures show that the shortage is not confined to a single category. Of 396 sanctioned motorman posts, 282 were filled, while 24 of 31 sanctioned shunter posts were occupied. The shortfall therefore affects both the staff responsible for operating passenger services and those supporting shunting operations. That distinction matters because train frequency and operating hours depend not only on rolling stock and tracks, but also on the availability of qualified personnel for each duty.
Kolkata Metro is already relying heavily on staff borrowed from other railway organisations. Of the 306 personnel on roll, 164 are on loan from Eastern Railway and 80 from South Eastern Railway. Together, the two zones account for 244 of the Metro’s running staff. The remaining personnel are permanently absorbed staff or running staff from other railway zones.
This arrangement has allowed Kolkata Metro to function despite the vacancy, but it also makes the network’s operating capacity dependent on coordination beyond the Metro administration. The Railway Board’s action plan asks Eastern Railway and South Eastern Railway to make suitable arrangements for the Metro’s staffing needs. It also directs Kolkata Metro to call for options from other railway zones to fill existing vacancies.
The Board’s assessment is that the additional requirement is relatively small when measured against the combined workforce of Eastern Railway and South Eastern Railway. It said Kolkata Metro’s need for 121 running staff represented 0.6 per cent of the combined on-roll running staff strength of the two zones, which stood at 17,506. The calculation provides the administrative basis for shifting personnel across the railway system rather than waiting for the Metro to fill all positions within its own establishment.
But the arrangement also points to a structural tension in urban rail management. A Metro network can expand its physical reach faster than it can build the workforce required to operate it. New corridors, longer operating hours and pressure for shorter headways increase the need for trained motormen and supporting staff. The infrastructure may be visible to passengers, while the staffing system that determines how frequently and consistently trains can run remains largely out of sight.
Kolkata Metro itself identified this pressure in a letter to the Railway Board on August 24. It said the network had expanded considerably and was continuing to expand to meet growing demand for urban transportation. It also pointed to longer operating hours, demand for further reductions in headway and requests for additional services. According to the Metro, these developments had substantially increased the requirement for motormen.
The sequence of the two communications is important. Kolkata Metro first sought permission to source eligible running crew from other railway zones on a loan or deputation basis. The Railway Board then reviewed the existing strength of running crew at a meeting in New Delhi on September 2 and issued directions covering inter-zonal staffing, utilisation and periodic monitoring. The issue was therefore treated not simply as a recruitment gap, but as a network-wide workforce allocation problem.
The Board’s recommendations extend beyond borrowing staff. It asked Kolkata Metro to explore outsourcing or re-engagement against stationary posts and to withdraw running staff from stationary duties for deployment in train services. It also advised the Metro to improve staff utilisation and minimise its staffing requirements. These directions suggest that the administration is examining both sides of the problem: increasing the available operating workforce and reducing the number of running staff tied up in non-running duties.
That approach brings the organisation of work directly into the question of urban mobility. Passenger-facing service levels depend on how staff are classified, deployed and rotated across operational and stationary roles. A vacancy on paper does not automatically translate into a cancelled train, but a persistent gap can constrain the ability to add services or reduce intervals between trains. The supplied Railway Board communication does not state that current passenger services have been cancelled because of the shortage. It does, however, connect the staffing requirement to the Metro’s expanded operating hours and demand for more frequent services.
The figures also show the limits of treating network expansion as a construction-only exercise. Kolkata Metro’s request refers to an expanding network and rising demand, but the operational workforce has not grown in parallel with sanctioned requirements. With 121 posts vacant, more than one in four sanctioned running-staff positions is unfilled. At the motorman level, 114 of 396 sanctioned posts were vacant, while seven of 31 shunter posts were unfilled.
The issue is particularly relevant because urban rail capacity is experienced by passengers through service intervals, operating hours and reliability. A new route or extended line can increase the geographic reach of public transport, but its usefulness is also determined by how often trains run and whether the system can sustain those services. Kolkata Metro’s own letter links the demand for shorter headways and additional services to the need for more motormen, making the staffing shortage part of the network’s capacity question.
The institutional response is built around coordination. The Railway Board has asked Eastern Railway, South Eastern Railway and Kolkata Metro to hold review and coordination meetings every quarter and report progress to the Board. This creates a recurring oversight mechanism for a problem currently being managed through loans, deputations and redeployment rather than through a fully staffed Metro cadre.
The arrangement also shows how Kolkata Metro’s administrative position within the railway system shapes its operational choices. Instead of relying only on direct recruitment, the Metro is being asked to draw from the wider railway workforce, while the two neighbouring zones are instructed to support its requirements. The Board’s reference to the combined strength of ER and SER indicates that staffing is being viewed as a shared railway resource, at least for the purpose of addressing the immediate gap.
What remains unclear from the supplied material is how quickly the vacancies can be filled permanently, how long borrowed staff will remain available, and whether the proposed measures will support the further reduction in headway sought by Kolkata Metro. The Railway Board letter sets out an action plan and quarterly review process, but it does not provide a permanent recruitment timeline or state how the staffing model will change as the network continues to expand.
The central lesson is that Kolkata Metro’s expansion has created an operational requirement that cannot be solved by tracks, trains or stations alone. The network currently has 306 running staff against a sanctioned strength of 427, with the majority of those on roll already drawn from other railway organisations. The next stage of the response will be measured through inter-zonal arrangements, staff utilisation reviews and the ability to close the vacancy without weakening the wider railway workforce. The Railway Board’s quarterly coordination meetings are the stated mechanism for tracking that progress.
