520 CMR 5.10
Trackless Trains or Similar Devices
Operators must have a valid driver’s license and must be 18 years of age or older. All new
design criteria list in 520 CMR 5.10 shall apply to devices constructed after March 18, 2005.
(1) Data Plate. Each trackless train shall have prominently displayed a manufacturer’s data
plate. Such plate shall include the maximum number of cars the train or device can pull safely
and maintain proper braking. It shall also include the maximum number of passengers, as well
as the national tracking identification number.
(2) Design Grades. Where designed for a specific terrain or road configuration, that the power,
traction and stability of the system shall provide adequate margins for safety. The limiting
characteristics of the system as designed shall be permanently marked in a prominent position
within the cabin on the manufacturer’s data plate if provided.
(3) Couplings and Safety Chains. Towing mounts, hitches, balls and ball couplers shall be
capable of towing the loads placed on them. Safety chains or ropes shall be installed in
accordance with the manufacturer’s specifications.
(4) Brakes. A trackless train or similar device shall be fitted with the following minimum
braking requirements:
(a) Travel Brake. Prime movers shall be fitted with a travel brake system capable of
stopping the fully loaded towed train under all designed conditions.
(b) Parking Brake. Prime movers shall be fitted with an additional braking system capable
of holding the fully loaded train stationary. A combination travel/parking brake may be used
only with the prior approval of the Department and for devices carrying less than eight
patrons.
(5) Steering. The carriage steering configuration shall provide stability under all conditions of
operation, and the turning circles of the prime mover and carriages shall be compatible and
suitable for the application of the train.
(6) Drawbar Capacity. The capacity and configuration of the drawbar shall be consistent with
the designer’s or manufacturer’s recommendation for the number of carriages to be towed in any
particular application.
(7) Center of Gravity. The center of gravity of any carriage should be as close to the operating
surface as possible, and information regarding the maximum allowable sideways inclination
should be displayed within the cabin.
(8)
Use of Spring Suspension. Spring suspension shall not be used without some shock
absorbing and movement limiting devices.
(9) Additional Safety Features. Wheels should not protrude beyond the sides of the carriages
and the gaps between carriages should be fitted with safety screens to prevent access between
carriages and across the drawbar. These additional safety features are to ensure that there are no
accessible pinch points or hazards that could catch a patron’s clothing or long hair.
(10) Other Traffic. Where the train or similar device is operated with other vehicle traffic
present, doors shall be fitted with catches which are operable only from the outside of the
carriages. If trains or similar devices are operated on open public roads, they shall be fitted with
vehicle and trailer signal systems. Where trains or similar devices are operated with other foot
traffic, the operator shall drive the device in a manner that does not present a safety hazard to
pedestrians. Operators driving recklesslyshall have their permit to operate immediately revoked
and shall not be re-issued a permit until a Department hearing has taken place and the appropriate
action has been taken to ensure rider and pedestrian safety.
