Rolling stock application solutions

CM4 has the experience and the resources to develop any kind of solution related to the functionality of rolling stock applications at any stage of development, from the description of the technical specification of a component to the design and construction of test benches and required training.

CM4’s quality system meets transportation requirements and the key standards ISO 9001:2008 and EN 15085 CL4, and product assurance that is fully compliant to EN 50125, EN 50126, EN 50128, and EN 50155.

Front hatch mechanisms

Our mechanisms are suited to a wide range of requirements, customising the design to be installed in any type of front nose. CM4 offers the best quality and long product life with low maintenance and at a competitive price, giving advice and support to the client in its implementation on the train and performing all the necessary tests.

Our train-to-train infrared remote control is a tailor-made solution for any mechanism that communicates with both trains, enabling it to carry out the coupling manoeuvre automatically.

We have also designed and developed front nose projects in collaboration with composite parts manufacturers.

We have installed more than 2,500 front hatch mechanisms on trains during the last 15 years.
