109 Shape corrected Appearance

The drawing did not match the connectors: the second track was missing and the crossover was a straight diagonal with a 76° curve (R 9.5 cm). Now two tracks 5 cm apart and the crossover as a #6 S-curve (curve R 115.1 cm / 9.5°, straight, reverse curve; 49.3 cm), length 49 instead of 30.7 cm, connectors unchanged. Source
110 Shape corrected Appearance

The drawing did not match the connectors: the second track was missing and the crossover ran as a steep straight between the wrong connectors. Now two tracks 5 cm apart and the crossover as a #6 S-curve (curve R 115.1 cm / 9.5°, straight, reverse curve; 49.3 cm), length 49 instead of 13.4 cm, connectors unchanged. Source
112 Shape corrected Appearance

The drawing did not match the connectors: the second track was missing, only one of the two crossovers was drawn (as a straight diagonal), plus a cross stub. Now two tracks 5 cm apart and both crossovers as a #6 S-curve (curve R 115.1 cm / 9.5°, straight, reverse curve; 49.3 cm each), length 49 instead of 5 cm, connectors unchanged. Source
