At 6 o'clock in the morning, more than 50 staff members were arranged neatly at the maintenance project site of China Railway 20th Bureau's Nacala Corridor Railway in the suburbs of Malama City, Nampula Province, Mozambique. After putting on work clothes, wearing work hats, inspecting work equipment, and assigning construction tasks... all preparations are ready, everyone takes a commuter bus to the construction site to engage in intense work. "The maintenance of the overturning machine at Nacala Port caused the suspension of the line, and the owner carried out emergency maintenance on the entire line. Among them, the PK433 and PK445 sections had severe damage to the steel rails, and we need to complete a total of 334 aluminum hot welding and hoisting work on the two sections within 10 days." Zhu Wenqiang, the manager of the maintenance project department, introduced that in order to complete the repair task as soon as possible, after receiving the notice, they only completed the preliminary work of on-site survey, construction of access roads, and leveling of the work site in 3 days, and mobilized personnel and equipment from about 500 kilometers away. Aluminum hot welding operations are most afraid of encountering water. In February, the local rainy season brought many difficulties to the construction, making the schedule even more tight. Zhu Wenqiang said that they have set up a mobile rain shelter on site, and wherever it is welded, the rain shelter will slide onto the track to ensure that work can continue on rainy days. "More than 20 mechanical equipment were invested in this emergency repair, and everyone stayed at the construction site throughout the Spring Festival period," said Zhu Wenqiang. At the Nawachi Station in Malawi, 200 kilometers away, Chinese builders are also racing against time to complete the construction. The Mozambique Nacala Corridor Railway has a total length of 912 kilometers, starting from the Moatize mining area in northwest Mozambique, crossing Malawi from west to east, and reaching the third largest port in Mozambique - Nacala Port. China Railway 20th Bureau undertook the construction of 650 kilometers and participated in the maintenance work after completion. In early 2016, the railway was completed and opened to traffic, with several heavy-duty trains transporting coal from the Moatize mining area continuously to the port of Nacala and then to various parts of the world. The construction of this railway has driven the regional economic development, improved the employment and living standards of local residents, and is therefore known as the "economic transportation lifeline of Mozambique". At the end of 2018, China Railway 20th Bureau entered Malawi and began participating in the maintenance work of the Nacala Corridor Railway within Malawi. Most sections of the Nacala Corridor Railway in Malawi still use wooden sleepers from the last century. In recent years, the railway transportation volume has continued to increase, and the local railway department has decided to upgrade and renovate the lines. "Within 10 days of the railway shutdown, we will replace over 700 concrete sleepers for turnouts, with the longest weighing 1 ton. Due to terrain limitations, manual replacement is the only option, resulting in high labor intensity and construction difficulty." Deng Jing, the head of the Malawi Railway Comprehensive Service Project, said he is responsible for the entire construction area of Malawi, which is 235 kilometers long. To ensure the construction progress, they divided four work points and invested corresponding personnel and mechanical equipment according to the different construction conditions of each section. Welding and handling of sleepers, mechanical roaring at the sleeper replacement operation point at the Naweichi train station. Kundewani, a 38 year old Mozambican employee, led 40 workers to work intensively along the railway line. Kundewani is Deng Jing's capable assistant in this sleeper replacement construction
