Subchapter II - Snowmobile Rail Crossings
Section NR 6.43 - New snowmobile rail crossing standards

(a) The rail authority or its contractor shall construct the portion of the snowmobile rail crossing for which the rail authority has responsibility.

(b) All other construction of the snowmobile rail crossing shall be performed by the snowmobile organization or its contractor.

(a) Horizontal alignment. The intersection between the snowmobile trail and the railroad track shall be as close to 90º as possible, but may not be less than a 70° angle on either side of the track. The alignment within 30 feet of the outside rail on either side shall be a straight line.

(b) Vertical alignment. The surface, without snow, of the snowmobile trail approaching the crossing for a distance of 26 feet from 4 feet outside the nearest rail may not be higher than one foot lower than the top of the nearest rail or 1.5 foot lower than the top of the nearest rail.

(c) Drainage. Where the grade of the snowmobile trail approach descends toward the crossing, provisions shall be made to intercept surface and subsurface drainage and discharge it laterally. Routing of drainage may require ditches, culverts, french drains, piping, geotextile fabrics or combinations of these improvements.

(d) Train speed. Public snowmobile trail crossings may not be sited across rail lines where the maximum allowable speeds through the section of track exceed 69 miles per hour.

(e) Sight distances. The snowmobile rail crossing shall be located so that when stopped on the crossing approach at the crossbuck and posted STOP sign, the snowmobile operator has a sight distance along the tracks in both directions, free of obstructions, to determine whether a train is approaching. The position from which the sight distance is measured is 15 feet outward from the nearest rail. The sight distances set forth in Table 1 for the corresponding maximum allowable train speeds shall be available in both directions from this position. Snowmobile rail crossings may not be sited at locations where sight distances are less than specified in Table 1.

Table 1

(a) Responsibility. The snowmobile organization shall be responsible for furnishing, installing and maintaining in a legible condition all signs identified in this section.

(b) Signs at the crossing. A railroad crossing sign, commonly identified as a crossbuck, shall be used to notify the snowmobile operator of the railroad crossing. The crossbuck shall be 2 panels 24" long by 4.5" wide mounted perpendicular to each other at the midpoint of each with the legend RAILROAD and CROSSING, respectively. The sign color shall consist of white reflective background with black lettering. The size of the lettering shall be 2". The sign shall be doubled sided and constructed with commercially manufactured reflective sheeting applied to an aluminum or treated wood backing. Where physically possible, the crossbuck sign shall be located on the right hand side of the trail. Where circumstances do not allow the posting of the crossbuck on the right hand side of both approaches, the crossbucks may be posted on the left. The crossbuck shall be erected 10 feet outward from the nearest rail and no further from the trail edge than 6 feet. The panels of the crossbuck shall be mounted so that the panels cross approximately 7 feet above bare ground on a preservative treated 4" x 6" post with the 6"side parallel to the tracks. The post shall have a 2" reflective white panel on both sides extending from 6" below the intersection of the crossbuck blades to 6" above the anticipated level of snow. A minimum of one crossbuck shall be used on each approach to the crossing. An additional crossbuck may be posted on the left hand side of the trail at a distance of 10 feet outward from the nearest rail. If the number of pairs of tracks is 2 or more, the number of pairs of tracks shall be indicated with 2 auxiliary placards. The first placard shall be 41/2" by 41/2" square placard placed beneath the crossbuck with the legend indicating the number of tracks. The second placard shall be 131/2 " by 41/2" rectangular placard placed beneath the square placard with the legend TRACKS. Both placards shall have a 2" black number or letters on a reflective white background. A STOP sign that complies with s. NR 50.09(4) (c) 3. b. shall be posted beneath the crossbuck at a level approximately 42" above the anticipated level of the snow. An additional STOP sign may be posted on the left hand side of the trail. Please refer to the following illustrations.

(c) Signs prior to the crossing. Prior to the snowmobile rail crossing, the snowmobile trail shall be signed with an advance caution railroad crossing sign. This sign shall be a circular sign of minimum 12" diameter. Sign color shall be a reflective yellow background with black letter and legend. The letters shall be 4" upper case and the black legend shall be 2" in width. Please refer to the following illustration. The advance caution railroad crossing sign and an advance caution "Stop Ahead" sign meeting the requirements of s. NR 50.09(4) (c) 3. b. shall be placed in a manner to enable a snowmobile operator to come to a safe stop at the crossbuck and STOP sign.

(a) The approaches of the snowmobile rail crossing may be all aggregate or a combination of aggregate and asphalt. The height of the approach installed by the snowmobile organization shall match the height of the crossing established by the rail authority. Crushed aggregate shall be thoroughly compacted with a roller vibrator. Where asphalt is used in combination with a crushed aggregate base, the asphalt shall be a minimum thickness of 3", installed in 2 equal layers. Asphalt material used for an approach shall conform to Section 407, Wisconsin Department of Transportation (DOT) Standard Specifications for Highway and Structure Construction, 1996, incorporated by reference herein. Crushed aggregate shall be grade 2 or 3 in accordance with Section 304 of the same publication.

Note: Copies of the DOT Standard Specifications for Highway and Structure Construction, 1996, are available for inspection in the offices of the Department of Natural Resources, Secretary of State and the Legislative Reference Bureau in Madison. Copies may also be purchased from the Department of Transportation, P.O. Box 7910, Madison, WI 53707-7915.

(b) A snowmobile organization shall properly dispose of all unused materials from the construction of the portion of the crossing for which it is responsible.

(c) A snowmobile organization may contract out the construction of the portion of the crossing for which it is responsible.

(a) No person may construct a snowmobile rail crossing that is not located on a railroad crossing of a highway or street unless the person is a snowmobile organization and has a permit issued under this subchapter.

(b) A separate permit is required for each snowmobile rail crossing constructed under this subchapter.

(c) A snowmobile organization may contact department regional offices for prescribed application forms and instructions. An application submitted under this section shall include adequate descriptions and drawings showing the proposed location of the snowmobile rail crossing, the proposed design of the rail crossing, a list of materials needed to construct the portion of the crossing for which the snowmobile organization is responsible and the location of snowmobile trails that connect with the snowmobile crossing. The completed application form with necessary attachments and the $150 application fee authorized under s. 350.138(5) (a), Stats., shall be submitted to the appropriate department regional office. Upon receipt, the department shall send a copy of the application to the agent of the applicable rail authority designated under s. 350.138(2m), Stats. The department may reject an application within 15 days after it is submitted if the application is incomplete or is not sufficiently detailed to determine whether to approve or deny the application.
