In our effort to diversify our product range, CM4 has designed a detrainment door model for subways. This model has been produced as a challenge to the company in order to assess the feasibility of manufacturing such products. The results have been very positive making a design that meets all requirements at a very competitive cost.

The design of this detrainment door is not made based on any particular vehicle but the object of this process of R & D has been to communicate to our customers our ability to manufacture this type of devices.




The manufacturing of these doors can be done according the next characteristics:


• With or without window
• Evacuation mode
-> train to train
-> train to track
-> both
• Opening way 
– automatic
– manual
