TT120 Scale Level Crossing

Hi All
First post.
This is a design at TT120 scale for a simple level crossing. However I have not successfully test printed it. My own basic (but grand!) Anycubic Cobra Go does not have the capacity for the needed detail. If you manage to print it, please let me know. Thanks! I'm sure more expensive FDMs would manage, but likely resin is the way to go! Suggestions/improvements are very welcome.
