... that the additional V-crossing will be positioned at 4. In deciding whether this will be acceptable there are several things to look out for: a. As explained in 3 above, it normally needs to be at least 14" scale from the nearest adjacent running rail. We are ok here, with the new V-crossing overlaid at 4. b. It will need its own check rails, and there must be room to fit these. As you can see there is a potential conflict here at 5: 2_050938_380000000.png In this case we can deal with this by shortening the rail length and flare length to leave the required clear gap for wheel flanges, as before. In other cases the conflict may be too much -- i.e. the V-crossing is not in a tenable position and must be moved by changing the base turnouts. c. The V-crossing must not be too closely opposite* another V-crossing, otherwise it will conflict with that crossing's check rail. Here at 6 you can see that even though ...
