Safety issue
| Safety issue description |
The location of sanding nozzles (for braking) behind the wheels of the lead bogie was inconsistent with design practice existing at the time of the collision and was probably a recurring factor in diminished sander effectiveness on VLocity trains. |

| Action description |
V/Line has advised that sanders have been installed, and are operational, on the intermediate (TM) cars of all VLocity three-car sets (Figure 32). In braking and powering, the TM car sanders discharge sand in front of the wheel-rail contact point (in the direction of travel). V/Line advised that when braking with the DM car leading, sand is discharged from units DM11 and TM12. When braking with the DMD car leading, sand is discharged from units DMD11 and TM11.
