4.8 RAIL TEST, WELD-OUT, & FINAL ADJUSTMENTS
4.8.1 Rail Test
After aligning the Railgear and adjusting the rail wheel loads, put the vehicle on a segment of
suitable test track and run the following tests:
 Run vehicle forwards and backwards on rail.
 If available, run the vehicle through curves and switches.
 Verify that the vehicle has sufficient traction to accelerate and brake smoothly and
within acceptable distances.
 Verify alignment by observing the wear pattern on the wheel and the behavior of the
vehicle. If adjustments are made, re-check alignment and weight settings.
After the Railgear has been aligned and tested satisfactorily on rail, it is necessary to perform
final welding procedures to ensure the safe and repeatable operation.
4.8.1 Weld-Out & Final Adjustments
****WARNING****
Select components of RW-1016 Railgear assemblies have been
hot dip galvanized. DMF recommends grinding off the galvanized
coating to raw steel where welding is required.
For vehicles with installed wireless Railgear controls, remove all
electrical and antenna connections from the Cervis base unit
before welding on vehicle or attached railgear components.
After a successful rail test, the following tasks should be completed to finalize the Railgear
installation. Always repaint any ground or welded areas to prevent corrosion. See Drawing
M101606 on the following page.
 Weld off square washers to adjustment collars (top edge only, 2X side)
o
Preserves alignment adjustment
 Weld off suspension assemblies to swing frame (1X/side)
o
Preserves alignment adjustment
 Adjust rail sweeps to contact rail
o
Ensures proper function
 Adjust droop-limiting bolts with gear in stowed position (optional)
o
Reduces suspension downtravel, but will limit noise/movement in
suspension when in highway position.
