Low Profile Rail Cart Improves Tunnel Access for Maintenance Crews

Rail maintenance inside tunnels comes with one major constraint—space. To get equipment where it’s needed, Sound Transit uses a Dymax Low Profile Machinery Cart.

This cart features integrated side ramps for unloading man-baskets and aerial lifts directly onto tunnel platforms. A steering tow hitch and off-track wheels add versatility, allowing the cart to be moved off the tracks without a crane.

Built for tight spaces, trusted in the field.

Sound Transit’s success shows what the right tool can do in the right environment.
