For a rail job, the ATC 3750-IP7-WI6CR is the better fit on the three points you asked about. It takes a wider, higher input voltage (24–110 V), runs up to 70 °C instead of 60 °C, and lists EN 45545-2 as well as EN 50155. Both are NEXCOM Edge AI Box PCs built on Jetson AGX Orin.

What this means for rail:
- Power: Neither range covers the other. The WI6CR goes up to 110 V but won't accept anything below 24 V. The 6C tops out at 36 V. You'll need to match the range to your train's supply voltage. nexcom.com +1nexcom.com ↗“power.power_input=24-110 V”nexcom.com ↗“power.power_input=9-36 V”
- Temperature: For both models, the operating temperature depends on the power mode and how much PoE power you draw. At high power and full PoE load, you may not get the full 60 °C or 70 °C. nexcom.com +1nexcom.com ↗“thermal.operating_temp_condition=Depends on power mode, Depends on PoE load”nexcom.com ↗“thermal.operating_temp_condition=Depends on power mode, Depends on PoE load”
- Certifications: Both list EN 50155. Only the WI6CR lists EN 45545-2. Only the 6C lists E13. Before you commit, check the certification details in NEXCOM's datasheets: ATC 3750-IP7-6C and ATC 3750-IP7-WI6CR. nexcom.com +1nexcom.com ↗“UKCA, EN50155, EN45545-2”nexcom.com ↗“UKCA, E13, EN 50155”
