Station Closures and Overcrowding
The knock-on effects of the rail disruption extended to the London Underground. Transport for London closed Euston Underground station due to overcrowding, as passengers sought alternative routes. Some Northern line trains were reportedly not stopping at Euston as a consequence of the intercity service problems.
Passengers expressed their frustration on social media. One user, Nicola Ruth, shared an image of a crowded Euston concourse, describing the situation as a "Halloween horror" with all lines blocked. Another traveller, Akira Murakami, noted that trains were being cancelled one by one, prompting a search for alternative journeys.

Shamim Chowdhury, a foreign correspondent, tweeted just before 6 pm that there was a "massive signal failure between Camden & Euston station" with no trains arriving at Euston and a backlog of services extending north. She reported passengers were left with no information about when they would reach their destinations.
Service Resumption
By 8:30 pm on Saturday evening, Network Rail reported that some trains were beginning to pass through the affected section of track and reach Euston station. However, the full extent of the delays and cancellations throughout the day had caused considerable inconvenience for travellers.
In response to the issues, Avanti West Coast arranged rail replacement coaches to transport passengers between Euston and Watford, and also to Milton Keynes, to help bypass the affected area. The disruption also led to increased activity at Marylebone station as travellers sought alternative services.
