This Monday, June 29, a strike by the Railway Union paralyzes part of the Renfe network. 320 trains will be canceled, with minimum services of 73% on High Speed and Long Distance, 65% on Medium Distance, and 50% on Cercanías (commuter trains), rising to 75% during peak hours. Travelers, especially those starting their vacations, face delays and fewer options. Renfe allows changing or canceling tickets at no cost. It is recommended to check schedules and look for alternatives.
The fleet management algorithm facing unexpected stoppages 🚆
Renfe uses planning systems based on optimization algorithms to assign drivers and rolling stock. During a strike, these systems must recalculate routes in real-time to comply with the minimum services required by law. The programming logic prioritizes high-demand lines and medium-distance connections with less schedule flexibility. However, the lack of redundancy in certain single-track sections causes bottlenecks. The integration of traffic and occupancy data allows the Renfe app to offer ticket changes at no additional cost automatically.
The bullet train that stops because of a pending coffee ☕
While engineers dream of autonomous trains without drivers, the reality is that a strike leaves 320 trains in the depot. Minimum services are like that friend who says they'll arrive in five minutes but takes half an hour: they comply, but not entirely. For travelers, the option is clear: check schedules or resign yourself to making the trip by car with a broken air conditioner. Of course, at least Renfe allows cancellations at no cost, a luxury that the gas station does not offer.
