Hi Feng,

it looks like the EN50155 is a system specification for Railways.

With the devices we can guarantee the device level and quality specifications has provided by the product page. (Link to Quality can be found the the ordering and quality table).

You should also consider the Q1 device with there is a request for a higher quality standard.

Best regards,

Stefan
