When the VHD is empty, the result of number of vehicles counted in the VHD comes to 1, while I expect to see the number zero.

The determination of train length does go well. Train AC 40 has left VHD and the Length comes to zero.
If a train composition has arrived on the VHD ( PF1 ) Platform 1 is nicely listed a train with a length over the Buffers of 66.5 cm and consisting of 2 units ( Autocoach and a Pannier )

What am I doing wrong ?

yours sincerely
