Thick fog hugged Delhi–NCR and western Uttar Pradesh early on Wednesday, February 4, sharply reducing visibility and slowing premium trains on key corridors. Rail officials reported cascading delays on routes linking the national capital with Lucknow and Varanasi, leaving many Vande Bharat passengers relying on last‑minute alerts rather than timetable precision this morning. The dense fog followed an overnight build‑up of moisture and stagnant, cold air across the plains.

Low visibility conditions developed after midnight and intensified around daybreak, with Safdarjung and Palam stations previously recording visibility near 50–100 metres during similar spells this week. Operations staff in Delhi Division said dense fog across northern sectors had already disrupted more than twenty Delhi‑bound trains since Tuesday, and warned that punctuality would remain under pressure through Wednesday morning.
Dense fog delays Delhi–Varanasi Vande Bharat today
The flagship Varanasi–New Delhi Vande Bharat Express, train 22415, was among services hit as schedules slipped in the fog belt. A delay of about two hours was recorded on the inbound run towards Delhi, according to a consolidated morning update on premium trains affected by dense fog conditions around the capital. Railway officials said further bunching was possible if visibility dipped again along the Yamuna and Ganga plains.
Operational managers explained that even semi‑high‑speed services like Vande Bharat must run under severe speed restrictions when dense fog sets in, despite their advanced signalling and braking systems. Safety protocols require drivers to proceed only as far as signals or track conditions are clearly sighted, stretching sectional running times. A Northern Railway spokesperson has earlier underlined that such winter disruptions are “normal during this time of the year” when visibility collapses.
Delhi–Lucknow premium trains also slowed by fog
On the Delhi–Lucknow corridor, passengers faced similar uncertainty, with premium services encountering pockets of dense fog over western and central Uttar Pradesh. The India Meteorological Department has issued an orange alert for dense to very dense fog over Uttar Pradesh and adjoining Delhi region till February 4, warning that transport disruption is likely along major rail and road links. Officials said crew are being briefed at originating stations to expect extended control instructions and speed checks.
Railway control rooms indicated that several long‑distance trains approaching the capital from the east were running late by one to four hours as of Tuesday, and fog bands were expected to persist into Wednesday morning over the Indo‑Gangetic belt. Passengers connecting from these services to afternoon departures towards Lucknow and Varanasi were advised to factor in missed connections and monitor live status before heading to New Delhi, Anand Vihar or Ghaziabad stations.
Live status tools and helplines for Vande Bharat passengers
To manage the disruption, Indian Railways has urged travellers to check the National Train Enquiry System (NTES) website or mobile app and location‑based SMS updates for real‑time running information before leaving home. In addition, passengers can call the railway enquiry number 139 or use RailMadad, the integrated helpline platform, for assistance on delays, coach positions and platform changes on affected Vande Bharat and other premium trains.
| Service | How to access | Key use during fog |
|---|---|---|
| NTES live status | Website / mobile app | Check updated arrival, departure and delay |
| Railway helpline 139 | IVR / SMS | Basic train timing and rescheduling queries |
| RailMadad | App / web portal | Register complaints, seek on‑journey assistance |
Refunds, rescheduling and what passengers should expect
Railway officials said fog‑related delays alone do not automatically trigger compensation on Vande Bharat services, since weather disruption is treated as a force‑majeure operational risk. However, if a train is formally cancelled or partially cancelled, full refunds are admissible under existing passenger rules, whether tickets were booked through counters or online via IRCTC, subject to standard timelines for claims.
In cases where passengers voluntarily choose not to travel due to anticipated fog but trains still operate, normal cancellation charges apply; if the railway initiates cancellation or marks a train as “cancelled,” refund is processed automatically for IRCTC bookings. Passenger associations emphasised that checking live status just before leaving home, carrying buffer time for airport‑style security checks at major terminals and planning flexible connections remain the most practical safeguards for Vande Bharat users on fog‑prone mornings like today.
