The correct answer is B. BSLB to Ad. Starter.
A station section is the section of track between two adjacent stations. In a double class B station, equipped with MACLS, the station section is situated between the BSLB (Block Section Leaving Balise) and the Ad. Starter (Automatic Train Starting).
The BSLB is a device that is used to detect the presence of a train on the track. It is located at the beginning of the station section. The Ad. Starter is a device that is used to start a train from a station. It is located at the end of the station section.
The station section is important because it allows trains to safely pass each other. The BSLB and the Ad. Starter work together to ensure that only one train is in the station section at a time.
The other options are incorrect because they do not represent the correct location of the station section. Option A, Home signal to Ad starter, is incorrect because the home signal is located at the entrance to the station, not between the stations. Option C, FP to LSS, is incorrect because the FP (Fixed Point) and the LSS (Leading Side Signal) are located at the entrance to the station, not between the stations. Option D, A or B any one, is incorrect because only option B is the correct answer.
