How do multiple rail transfers work under the Enhanced Transfer Rules?

Station pairs in close proximity include:
Bras Basah > Bencoolen
City Hall > Esplanade
Bencoolen > Dhoby Ghaut
Rochor > Jalan Besar
Downtown > Marina Bay
Raffles Place > Telok Ayer
The new transfer rules are for transfers between different stations, not within an interchange station. Therefore, these rules will not apply to Bukit Panjang, Newton and Tampines MRT stations as these are designated as interchange stations.
Commuters who change lines at these interchange stations by tapping out and tapping back in will not be considered as having made a transfer. They will be charged based on the shortest travel paths between their origin and destination stations, without incurring any additional boarding charges.
