MY OF MrrMM . • PURCHASING DEPARTMIUff • 155 PARKWAY ROUIBVARD • COPPBJ]., TEXAS 75919 AIM WRUBBER SHIMLESS FULL D Introduction A top quality, shimless, full -depth rubber OMNI railroad- highway crossing installation is depen- dent upon a properly prepared roadbed and ballast section, correct placement of ties and accurate rail gauge. Meeting these three condi- tions will insure a fast, cost efficient installation with minimum traffic Inconvenience. An OMNI crossing system consists of custom molded gauge and field panels, Camrail timber screws, and rubber plugs. It is an easy system to install, and its simple design allows custom fitting to complex track structures located within the crossing boundaries. General Instructions VW MELD PANEL - RAIL J_\ GAUGE PANEL 2 '�' - 1� • OMNI strongly recommends that the person who will be directly supervising the installation contact OMNI as early as possible to confirm crossing data and installation schedule. ♦ Ties must be located on correct spac- ings in order to properly support ends of panels. Beginning near the center of the cross- ing, on a six foot increment from one side, each tie should be placed at a nominal 18 "c -c. Exact spacing requirements should be confirmed by OMNI prior to track preparation. Do not centertles according to hole locations In panets. • It is important that the top surfaces of ties lie in the same plane because the OMNI panels conform to the tie surface. Ties that are twisted or not set flat should be adzed or replaced. This is especially important for ties which support panel ends to avoid offset of the panel joint. • OMNI panels are designed to fit either 9' -0" or 8' -6" properly positioned ties. Field panels are rimmed In the plant to accommodate 8' -0" ties. However, OMNI encourages use of onger ties at crossing installations. • OMNI panels are a nominal 6 foot length but 3 foot lengths can be supplied. ♦ -amoed ballast surface must be below top or -ie. • OMNI panels are designed to fit the rail pa `ern. Any protrusion, such as angle bars, require field trimming to provide relief. Use of welded rail through the crossing eliminates most of this trimming. Note: Welds must be ground smooth to avoid interfering with panels. • If rail anchors are required in the cross- ing area, customer should discuss RUBBER PLUG brand of rail PANEL ! / anchor prior to shipment of OMNU order. Certain brands minimize - interference with the OMNI panel. The Unit IV Drive -On Rail Anchor is recommended. * OMNI panels are secured to each tie with hian strength Camrail timber screws. Panels for tangent crossings will normally be counter - bored at the plant and the screws are driven so that the screwhead just comes in contact with the bottom of the counter- 1 bore hole. A rubber plug is placed over each screwhead and driven flush to the panel surface with a sledge hammer (spike mauls should not be used). If a screw is either over- driven or underdriven, the top of the plug will not be flush. ♦ Ties should not have to be predrilled unless a hole in the panel is located over a knot in a tie. If predrilling is required, use a `I," auger bit. • Camcar timber screws have a TORX socketed head. TORX bits and adaptors to fit 1" drive impact wrenches are generally not standard equipment for a track gang. OMNI provides one of these items with each crossing. It is packed in a specially marked hardware box. Additional TORX bits and adaptors can be purchased from OMNI. • OMNI , Hill orovide a field technician free of charge to make recommendations prior tc and /or During installation. However, OMNI field tecrnicians cannot oversee or direct installer's employees. Tangent Crossing Installation LIFT AT MID -POINT OFPANEL Rail Tongs Step 1. Select a tie near the middle of the crossing so that the distance to both ends of the crossing is in g or b' increments. This will allow all panels to be positioned correctly over the ties for fastening. Begin by placing a gauge panel in position toward one rail and align the long edge over the rail gauge centerline. Step 1 If panel doesn't easily slip under ball of rail, hold pressure against panel with prybar and tap down in flangeway with spike maul. Panel will bounce into place. Do not fasten this panel to ties until the second gauge panel is in place. Step 2 Step 2. Slide nose of opposite gauge panel over tie plate and, while standing on elevated edge, tap panel into place. Applying soapy water to the panels will make it easier to slide panels into place. It is often necessary to help guide nose of panel over fasteners by using a prybar or shovel to lift nose while being tapped into place. When panel is down on tie, pry panel back `« against first panel to make, tight centerseam. Fasten both panels to ties. Step 3. Align two field panels opposite gauge panels and fasten to ties while being wedged tlgntly against the rail. Step 4. Place remaining gauge and field panels irto position. Be sure to maintain centerseam on gauge centerline and to bump panels lengthwise to fit tight against previous panels. Do not fasten yet. Step 5. Place trackjack against ends of gauge panels to hold all joints tight and to align cross- ing ends. Maintain pressure until end gauge panels are fastened to ties_ Be sure to:ma tain a tight centerseam and to k se aiigned wit a ( gauge centerr irie Fasten remaining gauge panels.

Repeat procedure for field panels except individual field panels must be held t ght against rail while being fastened. 30" Timber Tongs so-15 Curve Installation IMPORTANT: Read thfsfnstruction Sheet before beginning work. This procedure must be followed when building curved track structure, as the tie plates may be slightly skewed on the ties. Step 1. Determine where the end of the OMNI rubber surface will be at each edge of the roadway on the outside rail of the curve. Then measure on that rail to the 6' increment nearest to the center of the crossing. This is where your center tie will be placed. For instance, on a 66' crossing you would either go to 30' or 36' for your center tie, not 33.' Step 2. Put a mark on the top of the outside rail where your center tie is going to be. With the use of a track gauge, square across to the inside rail and mark it on top of that rail. Step 3. Center your first tie on these two marks and install rail anchors. Step 4. Measure out 72" on each rail in both directions from the center tie mark until you reach ends of the crossing. Step S. With the use of a T square, line up on the first 72" mark away from the center tie mark on the outside rail and move the tie so that the center of the end of the tie lines up with the T square. Step 6. Repeat this procedure on the inside rail with the other end of the tie and install rail anchor so that tie will not move. Step 7. Recheck the outside rail with T square and align. Then install rail anchors so that this end of the tie will not move. Step 8. The three ties in between can be done the same way on approximately 18" centers, but every 5th tie is the critical tie as the panels butt together on these ties. Step 9. Repeat steps 5, 6, 7 and 8 until you reach the limits of the crossing on both sides. You can go up to 60' in each direction from the center tie for curves up to 15 using this method without having to cut panels. RIEDlL offla PRODUCTS, INC. P.O.
