Added poling pockets to the front and rear pilot beams. Pockets are UV mapped to the pilot and cab/wheels areas to avoid the need to change the texture. These changes, like the earlier drivetrain revamp, are automatically inherited by any liveries using the default frame.

Fixed clipping snow mesh caused by reshaped engine housing.

Significantly improved cylinders and driveshaft meshes, added missing crankcase, minor changes to frame and boiler details.

I was planning on doing fully authentic trucks in addition to these updates for the 1-year anniversary of the mod, but unfortunately Rolling Line will not allow for the properly articulated driveshaft necessary for these trucks (which I already have modeled and ready to go) to look decent in-game. As such, I have retained the bulkier preset trucks as they somewhat hide the clipping caused by the non-articulated driveshaft. Perhaps someday the Shay will get its proper trucks, but for now it will continue to use the prefabs.

(Changing the trucks and driveshaft would also break every livery for it, since new wheel blocks aren't passed down to dependents. Just changing the body mesh and the existing single-mesh driveshaft avoids this problem, so all liveries still work fine and automatically include the remodeled cylinders and other changes.)

Added a narrow-gauge variant with mildly funky asymmetrical trucks.

Front and rear headlights now can be toggled independently (headlight and custom light 1). This may cause liveries made prior to the update to have missing light meshes, which will need to be fixed by the livery creators.

Collision support and climbable ladders!

Added custom bell colors (since those now work again)

Fixed driveshaft direction.
