Waterloo Trains Services: SWR Advises ‘Do Not Travel’ Amidst Widespread Disruptions

June 24, 2025, Commuters at London Waterloo and along South Western Railway (SWR) routes are facing major disruption today. SWR has issued a clear alert: “Do not travel”, due to a series of incidents disrupting Waterloo Train Services, leaving many routes heavily delayed or cancelled.

What’s Going on with Waterloo Train Services?

Chaos unfolded early this morning on SWR-operated lines into Waterloo, sparked by a derailment inside an SWR depot between Southampton Central and St Denys  . The derailment has impacted train availability and crew scheduling, resulting in a ripple effect throughout the network. Consequently:

• Several services have been cancelled or restarted from different stations.
• Some trains are running with fewer carriages (often reduced to 4 from 8) due to maintenance issues.
• Toilet facilities are limited on many services due to reduced coach counts.

With limited rolling stock and staff across the network, SWR is urging “Do not travel” for all non-essential journeys, especially during peak hours.

SWR Confirms Derailment in Depot Affects Morning Services

The derailment occurred early today in a depot between Southampton Central and St Denys. SWR confirmed that the force trains in that area will be canceled or adjusted, causing major disruption on key Waterloo Train Services . Engineers are currently working to clear the derailment, but remediation is expected to take several hours.

How Is the Network Coping?

SWR’s contingency response includes:

• Forming shorter trains on available routes.
• Restaffing crews across the affected lines to plug gaps.
• Repeating the travel advisory at all stations: “If you can, please do not travel” until further notice is given.

Despite these mitigation actions, the complexity and scale of disruption have left many services disrupted or cancelled, with ripple effects across London and the south-west commuter belt.

Disruption Likely to Last till Mid-Afternoon 

According to the live SWR disruption board, services between Southampton Central and St Denys remain affected until around 13:00 on June 24, and SWR warns delays could extend beyond that for affected routes into London . Passengers should allow extra time or consider postponing their travel until later in the afternoon.

SWR Enters State Ownership This Year

As of May 25, 2025, Southwestern Railway officially became state-owned under the Department for Transport. Despite this transition, the company continues to manage its own rolling stock, infrastructure incidents, and operational crises such as today’s depot derailment. Whether state ownership will accelerate future improvements remains to be seen, but amid today’s chaos, SWR’s Coordination with Network Rail and emergency services is under close public scrutiny.

What Should Commuters Do?

Commuters facing challenges with Waterloo Train Services should consider the following:

• Avoid essential travel until disruption notices are lifted.
• Delay journeys until after 13:00–14:00, or opt for alternative routes via Thameslink or GWR.
• Use SWR’s journey checker and real-time updates for changing train times.
• Contact SWR’s support staff at station help points or via the rail inquiry app.

Why This Matters

This incident isn’t just about today’s delays; it highlights structural flaws in Waterloo Train Services:

1. A single depot disruption can cascade across the network due to limited reserve rolling stock.
2. SWR’s new state‑owned status places pressure to show seamless crisis management.
3. Passenger trust and travel behaviour remain fragile: such incidents directly impact service reliability sentiment.

For many in south-west London and beyond, this morning’s travel chaos serves as a sharp reminder of how vulnerable Waterloo Train Services can be to unexpected events, and how critical real-time communication is in crisis.

Looking Ahead

SWR has promised:

• A full update once the depot issue is cleared.
• A review of buffer stock and contingency planning to reduce future risk.
• A post‑mortem after service restoration to assess response effectiveness.

Commuters are urged to stay tuned to official SWR and Network Rail updates and to plan travel only if absolutely necessary until the disruption subsides.

Final Thoughts 

The derailment in the SWR depot near Southampton Central has triggered severe interference across Waterloo Train Services. With many trains cancelled, multiple services shortened, and SWR actively advising “do not travel”, it’s a rough morning for commuters. State ownership has not prevented operational failure, but may offer an opportunity for improved response.

Right now, the advice is clear: stay local, stay put, and let SWR and Network Rail fix the depot. Only when they sound all clear should normal travel resume.
