The other element of their proposal to the European Commission includes selling the bulk of Alstom's signaling business in Europe in addition to some Siemens signaling assets, one of the people said.

German industrial group Siemens and French rival Alstom put in their offer last week, saying that it was made up mainly of signaling activities and stock products which made up around 4 percent of the sales of the combined company.

The companies have offered to divest either Alstom's Pendolino platform or Siemens' Velaro Novo platform, the people said.

Pendolino, which features a tilting technology that results in less braking before bends, is tailored for high-speed and conventional lines. Pendolino trains have been sold to 12 operators in 12 countries. Siemens' Velaro Novo high-speed trains, on the other hand, will only enter service in 2023.

The proposal includes a five-year license to sell the trains in Europe.

The signaling assets on offer include three-quarters of Alstom's signaling business in Europe, one of the people said. The package includes signaling for urban transport, mainline trains and conventional trains.

The Commission has given rivals and customers this week to provide feedback. A negative response could prompt it to demand more concessions from Siemens and Alstom before it makes a ruling by Feb. 18.
