Product Description

Modern Grade Crossing EXTENSION - Rubber Prototype History: Our Modern Rubber Grade Crossings are the first ever produced for N-Scale. We took our time in designing the grade crossings to ensure that not only were the measurements correct, but they looked right when mounted and worked correctly with 99% of the rolling stock available. Our rubber and concrete grade crossings are made to simulate two-lane highway crossings (expander pack available). Length: 2.5" Installation Instructions Download PDF Instructions To Mount: 1. Carefully remove all pieces from the etched-metal frame with a sharp hobby knife. 2. Before mounting, find the height (often called the Code) of the rail you're using. Code 55 track has a rail height of .055" while Code 80 has a height of .080" for example. 3. These etchings are .010" thick, so if you're using Code 55 rail that is .055" tall, you will need a shim (plastic strip) that is about .040" tall, leaving you with .005" of clearance below the rail head. 4. Mount your shims down the middle of the track and on either side of the ties where you would like your grade crossing to lay. Remove spike heads to aid in laying the shims flat if they are wider than the space between the spike heads. 5. Glue shims in place. 6. Glue the 3 long etchings in place, but, bend the ramps down so they lay just on top of the ties (the ramps are only on one end). 7. Next, you will notice that you have three of the short pieces (ramps) left over. The ramps are left off on one end to allow you to expand your grade crossing to a 4 lane road using our expander pack - BLMA #78 8. If you are not using the expander, simply glue the ramps onto the end of the long etching at the same angle downward as they are on the other end. To Paint: 1. The ramps on these models are metal and the rest of the crossing is a high-density rubber. 2. Simulate the rubber using thin washes of India ink or thin black paint. (An airbrush works as well.) 3. Because the ramps are to remain their natural metal color, we recommend weathering them (and the whole thing) with dull coat and perhaps a hint of orange or brown chalk dust to represent faint signs of rusting.
