The article is in in Spanish but basically says:
"The recent merger announcement between Alstom and Siemens will have direct effect in Spain where local firms CAF and Talgo, which have up until now been able to compete separately against those two giants, are now not only facing a new rival but also the fact that merger moves are driving the industry nowadays. Once again, the idea to create a Spanish giant is beginning to take shape again. Although no talks have started regarding this potential merger, it is known that both companies are interested in it. CAF, which is the biggest of the two, would benefit a merger with Talgo as it would help it achieve extra support from the Government. While CAF is in the hands of Kutxabank (14%) which has already expressed certain interest in selling, Talgo is under the control of Trilantic (35%). What makes Talgo attractive is the fact that it has recently won a EUR 1.5bn high speed train delivery contract. They are both complementary and while CAF focuses on light trains, Talgo specialises in high speed trains."
