Alstom and Siemens say the package aims to address the EC’s concerns while preserving the industrial and economic value of the merger.

The proposed measures include activities in the rolling stock and signalling sectors and represent around 4% of the sales of the combined entity.

The EC is expected to decide by February 18 2019 whether the proposed measures adequately address its concerns about the planned transaction.

The EC launched an investigation into the merger in July amid fears the deal could lead to “higher prices, less choice and less innovation due to reduced competitive pressure in rolling stock and signalling tenders.”

In September, the Australian Competition and Consumer Commission expressed concern over the potential impact of the merger on the signalling market in Australasia, while in October British infrastructure manager Network Rail wrote to the EC warning that the transaction “stands to do great harm to the railways in Great Britain.”
