In June 2020, twenty ballast hopper wagons manufactured by CRRC Taiyuan are set out by Taiyuan, and arrive at Tianjin port through road transportation. After the port is ready, they will be sent to Bangladesh by sea. These ballast wagons will be used to transport and lay ballast for the local railway construction projects.
Project Background
This batch of ballast hopper wagons is the first overseas complete wagon order we finished since our reopening after the strike of the COVID-19 pandemic. The total order amount is more than 15 million USD, which proves our capability of manufacturing quality hopper wagons during the pandemic.
During the epidemic, the raw materials, parts, and logistics transportation required for the production of this batch of Bangladesh ballast hopper wagons were affected to varying degrees. But we manage to effectively prevent the epidemic, overcome adverse effects, and successfully completed the production task on schedule under the premise of ensuring safety. After receiving the port notice, we organized the transportation at once to ensure the order will be delivered to Bangladesh on time.

Notable Features of These Ballast Hoppers
The brake systems equipped to these ballast hoppers were first Chinese domestic systems with EU UIC standard. It not only reduces the production cost but also shortens the production cycle, which plays an important role in the successful completion of this order.
The 1676mm gauge bogies developed for this batch of ballast hoppers are the first batch application of the company’s wide-gauge bogies in exported wagons, which lays a certain foundation for the company to open other wide-gauge railway freight wagon markets in the future.
