Just wanted to confirm the good news --
The 'current' 1.12 version of this plugin still appears to work with my new 1.14.2 spigot server (with the latest 1.14.2-v1-snapshots of Traincarts and BKCommonlib, of course)
I've loved using this in conjunction with Traincarts for years, simply for the fun of hopping in a Train, adding fuel, and manually controlling the vehicle for long hauls.. it's like a model train set right in your custom world.
Easy to use Traincart sign controls to activate track switches by holding a designated item in your hand (we use emeralds) and control where you are going at full speed. :)
Don't know if the author checks in here these days, but thanks if you do!
