Key points for a remote rail yard:
- All 10 support the Jetson Thor T5000 128GB and T4000 64GB modules (LI-THOR-CB lists Thor family support; the TT315 does not list specific modules). advantech...advantech.com ↗“compatibility.jetson_module=Jetson T5000 128GB, Jetson T4000 64GB”
- Every unit carries 1035 sparse INT8 TOPS on T5000-based configurations — the INT8 figure is sparse for Thor products. advantech...advantech.com ↗“performance.max_ai_tops=1035 TOPS, performance.ai_perf_basis=INT8 TOPS (sparse)”
- Coldest ratings: the Realtimes RTSS-X407 and RTS-AGT700 both go to −40 °C, but their ranges depend on power mode — the RTSS-X407's −40 to 60 °C is specified at 140W consumption. realtimesa... +1realtimesai.com ↗“The -40 to 60 °C temperature range is specified at 140W consumption”realtimesai.com ↗“thermal.min_operating_temp_c=-40 °C, thermal.operating_temp_condition=Depends on power mode”
- Airflow caveats: the Advantech units (MIC-742-AT, MIC-743-AT, MIB-741-AT, MIB-742-AT, EPC-T5294) require airflow for their stated temperature ranges. advantech...advantech.com ↗“thermal.operating_temp_condition=Requires airflow”
- The only fanless-capable option is the Forecr DSBOX-THRMAX (Fan/Fanless variants offered). forecr.ioforecr.io ↗“thermal.cooling=Fan/Fanless”
- The RTS-AGT700 is the only unit with two SFP cages; the Tauro TT315 is the only one with an IP rating (IP20) and MIL-STD-810H shock/vibration ratings listed. realtimesa... +1realtimesai.com ↗“io.sfp_ports=2”taurotech.com ↗“mechanical.ip_rating=IP20”
What I could not verify: none of these products lists an EN50155 railway certification in their catalog entries — certifications shown are CE, FCC, CB, UL, and similar. If you need formal rolling-stock/rail certification, that would have to be confirmed with each manufacturer directly. Also, LI-THOR-CB's operating temperature range is not listed in the catalog, so outdoor suitability there is unconfirmed.
I've asked above which site constraints matter most (fanless cooling, −40 °C operation, GNSS, DIN-rail/wall mounting) — tell me your picks and I'll narrow this list to the strongest candidates.
