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 4½″ by 4½″ square placard placed beneath the crossbuck with the legend indicating the number of tracks. The second placard shall be 13½″ by 4½″ 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.

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.

NR 6.43(4) (4) Scheduling and supervision of approach construction. The snowmobile organization shall schedule the snowmobile rail crossing approach construction with the appropriate railroad authority and Diggers Hotline [phone]). All work performed by the snowmobile organization within 25 feet of the track shall be under the direct physical supervision of the rail authority or with explicit written permission from the rail authority to perform the work without direct physical supervision. The snowmobile organization’s workers shall comply with the safety requirements established by federal and state law and the rail authority. The rail authority shall provide the snowmobile organization with a written copy of the rail authority’s safety requirements applicable to outside contractors who perform work on the rail authority’s property.
