A dual rail track approach span spline for the Merivale bridge (kuid2:60238:27225:1). To join to the Merivale bridge, place the main Merivale bridge, adjust the level to suit and find the height of the track nodes. Place the approach spans, and apply the height to the end nodes of the spline.
Select a single track spline, kuid:-1:100966, 4mstandard solid. Join track between the rails on the spline and the main span. Move the bridge approach spline to the main span to close the gap. Carefully align the spline with the span.
