VDS Rail's 28 ports Consist Switch is a 10-Gigabit/Gigabit/Fast Ethernet managed switch designed for network applications in Rolling-Stock environments. 

Layer2/Layer 3 managed switch

Besides providing wire-speed layer 2 forwarding capabilities, this switch also supports Layer 3 services, allowing IPv4 unicast and multicast routing among different VLANs. Layer 3 extensions include inter-VLAN routing with packet filtering together with NAT. OSPF and RIP dynamic protocols are also supported. 

Wide range of models available 

This Consist Switch supports up to five (5) 10GBase‑T Ethernet ports, eleven (11) 1000BASE-T Ethernet ports (4 with PoE+ capability), and twelve (12) 10/100BASE-T ports with optional PoE+ capability. Besides the standard features provided by this class of devices, this Consist Switch provides advanced software facilities for on-board network discovery and configuration.


This EN 50155-compliant switch is equipped with up to 2 bypasses, making the device completely transparent to the network in case of a power outage or failure.
