On30 Bridge Abutment

On30 Bridge Abutment

Edward T.
Description
This abutment is scaled for On30. I modified the RSE Bridge Abutment as follows: The Tie Seat was made for 8ft ties (seems reasonable for a On30 Bridge Tie) and is .112 in deep to fit some basswood ties I had on hand. It is scaled for a scene on my layout with the measurement being 2.226 in (8 ft 10-27/32 in) from the base of the rail to the water surface (indicated by where the gray concrete stops and yellow begins. All of the yellow footing is below ground). The Bridge Seat is 1.079 in (4 ft 3-25/32 in) deep. This fits the On30 bridge I kitbashed from a HO Central Valley Plate Girder Bridge and my custom Bridge Shoes. With those measurements set .. the other major factor in 'translating' from the original drawing is that the 'wings' are set back at 30° and slope at 1 to 1-1/2. With that .. you should be able to modify this to fit your scenerio. For standard gauge use the RSE Bridge Abutment which is the original, unmodified Standard Gauge abutment. #Abutment #Bridge #Concrete #On30
