Lucknow, Jul 30 (IANS): Power in the state capital and major towns of Uttar Pradesh limped back to normalcy Monday, eight hours after the Northern Grid tripped, while many trains en-route to and through the state were left stranded, officials said.

The power situation was almost normal in Lucknow and the eastern parts of the state, said an official.

Barring Noida and Kanpur, power had been restored to half the normal capacity, Avanish Awasthi, chairman and managing director (CMD) Uttar Pradesh Power Corporation Limited (UPPCL), told IANS.

"We have been able to successfully restore power in most parts of the state barring Noida, Greater Noida and Kanpur, but will soon tide over the crisis," the top official informed.

Many districts in the state plunged into darkness following the tripping of the Northern Grid at around 2.33 a.m.

The railway services were also affected due to the power outage.

Many important trains like the Lucknow-Delhi Mail and overnight trains plying between New Delhi, Lucknow, Allahabad and Varanasi, Moradabad, were stranded en-route, while some were being brought to the nearest stations by diesel engines, a railway official said.

All government hospitals, following the black-out, were put on emergency services and generator back up, an official informed.
