Cims across the end of station track

[muska 5]

Hello. I'm making a train station asset but there are some problems.

1. Almost of cims across the rail by pink path(in asset editor), but some of them don't use the path but they across the end of station track.

2. I would like to make platform asset which needs no roadside connection. Not circular but needs road snap when it be placed like konfox's platform. His platform needs road connection when it be placed but it don't makes 'Roadside required' icon after bulldoze the road.

Is there anybody know to solve these problems? Thank you in advance.
