It took 10 hours to get to Nairobi from Mombasa by train.

Local Kenyans have benefited a lot from the new railway. A government worker said, “I’m very happy with the new railway built by our Chinese friends. Manys changes have taken place in the town over the last few years, and the people who live here have become rich.” A businessman said, “My experience of using the train since 2017 has been good. It is very convenient and doesn’t cost much money. I am able to get to places on time and make business deals with ease.” The railway has also made the transport of food easier. Food used to take hundreds of lorries to carry between the two cities, but now it takes only two or three trains,” said a supermarket manager. As a result, people now have more fresh food to eat.
