The train arrived from Bokaro in Jharkhand.
In view of the high demand for oxygen in the country following a record spike in coronavirus cases, the Railways has decided to run Oxygen Express trains to transport liquid medical oxygen and oxygen cylinders across the country.
Tankers are being transported on flat wagons by the trains for quick supply of medical oxygen.
Two tankers of medical oxygen arrived in Lucknow around 6.30 am while one was offloaded in Varanasi, Additional Chief Secretary (Home) Awanish Kumar Awasthi told PTI.
Each tanker has a capacity of 15,000 litres, he said, adding that oxygen brought by two tankers may be used in Lucknow.
