Germany's DHL Global Forwarding has enjoyed increased interest in its temperature-controlled rail service from Chengdu to Lodz, Poland, said a company statement.

"Customer interest has been robust. During the winter season where average temperatures can dip to -20C and more along the rail route, customers can pre-define the temperatures for their shipments in the exact range of -25C to 25C," said DHL Global Forwarding Asia Pacific CEO Kelvin Leung.

"Temperature-controlled containers are individually powered and offer flexibility of controlling, tracking and modifying temperatures remotely through track and trace systems, which allow customers to be aware of their shipment's precise location," said Mr Leung.

"We are seeing an increase in demand across all modes of transport ahead of the year-end holiday season in particular, the temperature-controlled transportation option is especially useful for temperature-sensitive goods, such as certain electronics and high tech products," said Mr Leung.
