NMRA CV 140 - Active Quill CV
This CV controls which grade crossing quills can be played when the grade crossing button is pressed. There are 3 different types of quills loaded onto the decoder each with a different length, short, medium, and long quills. The can be played in order or have a random quill selected each time. Trains running in areas with large open areas can have long grade quills while trains in a city with many grade crossings close to each other usually play shorter quills. By default all quills are active and will play in random order. To play them sequentially enable the "Play Quills in order" setting.
To program this CV take the values in the values column corresponding to the features you want active and sum them together and program this value into the CV. See the table below for available options.
