Suggestion Request NEXL Railroad and Train Station for Cities XL and Cities XXL

I really like cities XL and I was thinking it should be a NEXL Railway and Train Station For Cities XL and Cities XXL, and it is no trains and train station for cities XL and cities xxl, also when I download railroad Mod some issues with connecting rail tracks and road with crossing the train tracks and we Needed NEXL Train Station Pack

I was wondering why is no NEXL Train Station Pack For Cities XL and Cities XXL

NEXL Train Pack would require:
- Rail tracks
- Rail Overpass
- Rail Bridges
- Road Crossings
- Train Stations
- Train Depot
- Train Warehouse
- Trains
- Train Parking Lot
- Train Tunnel
- Train Bridge
