Two sets of demo trains purchased by Nepal itself are being taken to India for maintenance after about 4 years of operation. India has already sent one set of its trains to Nepal during that period after the Nepali railway went under repair.

Both sets of trains from Nepal are going to be sent to Lucknow, India for repairs on Sunday. According to Niranjan Jha, Managing Director of Nepal Railway Company, periodical overhauling (POH) of both sets of trains will be done in Lucknow. 'This means maintenance of all parts to meet the opening of the train set.  This is a routine maintenance,' said Jha, 'On Sunday, both sets of Nepali trains are being sent to the workshop of Indian Railways in Lucknow. Until the Nepali Railway is repaired, the service will be operated by the train sent by India.

Nepal Railway Company Acting Administrative Officer Tula Dangi said that all parts of the Nepali Railway including wheels, engines, bogies and seats will be repaired in Lucknow. Some seats of the AC coach of Nepali Railways have been torn and broken. Dangi said that after the maintenance, all these problems will be removed.

Although India initially claimed the money for the railway route to be used up to Lucknow, later it said that the railway route, maintenance and a set of trains sent for operation during the maintenance period will not get the money. 

The managing director of Nepal Railway Company has issued a notice and stated that there are no AC coaches in the Indian trains running in Nepal during the maintenance period. The train sent by India does not have the AC coach facility. Jha said, "During the maintenance period, Indian Railways will operate three times a day from Jayanagar-Janakpur and once a day on the Janakpur-Bhangaha section." He informed that the train sent by India has 6 general bogies with a single engine. "In the train sent by India, engines can be attached on both sides," said Dangi, "but the train will be put into operation with a single engine."
