- automatic couplers don't catch above the safe collision speed (#86): with crash damage on they couple at a closing speed of 15 km/h at most, a faster hit locks the coupling until the vehicles part and the collision runs its course. On the way: CollisionVelocity() read a head-on 10 + 10 km/h as 14.1 km/h (quaternions turn by half the angle), it's now taken from the touching ends; CollisionDetect() took the other vehicle's speed the wrong way round for vehicles facing each other. Head-on hits now derail sooner, at the intended limit, - a single horn lever can't sound both tones at once (eu07/maszyna#392), - a skid ends once the vehicle stops on locked wheels (eu07/maszyna#479), - electronic destination signs are blanked at the end of the timetable (eu07/maszyna#446), - horns need the air or the voltage to sound (eu07/maszyna#290, #76): HornType=[Pneumatic]|Electric and Horn3Type in Cntrl.; a pneumatic horn needs 0.2 MPa in the main reservoir (or the main pipe without one), an electric one the low voltage; the lever stays where it was put, - compressor start delay (#67): CompressorStartDelay [s] in Brake., counted from the compressor getting its power, after the engine starts say; none by default, - the channel and volume buttons of a radio without power do nothing (eu07/maszyna#429); the power check of the radio is TMoverParameters::RadioPowered(), - a lever moved smoothly sounds the positions it passes (#83). Sonar findings in the functions changed: nesting, nested conditionals, commented-out code, std::format, references to const. Unit tests: test::pair for two vehicles running into each other, test_couplers, test_horn, test_wheelslip, test_compressor, test_radio, test_gauge_positions.
