Newly built Fuxing bullet trains going 160 kilometers per hour have no excessive formaldehyde problem and will be scheduled to be put in service in batches, according to a statement from China Railway Beijing Group Co Ltd.

The Beijing company released a statement on its official account on Sina Weibo, China's Twitter-like service, Monday evening to refute a mistaken report from China Business Journal from earlier that day.

According to the report, some sources close to the Beijing company said at least two branches of China Railway Corp, China's railroad operator, have received newly built Fuxing trains of 160 kilometers per hour with excessive formaldehyde problems and stopped running them.

The Beijing company said in the statement there was no such situation, and the reason that have not been used so far is due to long-term debugging and waiting for the "new car smell" release period to pass.

It said the trains will be arranged to be put into operation in batches.

Railway authorities pay high attention to passengers' health and environmental issues, trains deemed unfit for operation will not run, and they will request manufacturers to renovate and ensure quality, the report said.
