the Light Rail grade separation works on Pui To Road, the route was suspended in its entirety and replaced by bus route 506. The suspension was originally intended to be temporary, but the Light Rail route was never resumed. Fares The Light Rail is the only public transport system in Hong Kong to have fare zones and the only one with an honour system, in which there are no ticket gates. These fare zones apply only to passengers purchasing single-ride tickets from ticketing machines at LRT stops. Since the introduction of Octopus cards, however, passengers have a choice of ticketing options. All fares indicated below are for adults, while children and the elderly usually pay the concessionary fare, which is about half the adult fare. Single-ride tickets There are six fare zones – 1, 2, 3, 4, 5 and 5A – for passengers purchasing single-ride tickets in Light Rail stops. Zone 5A was introduced solely for the latest extension in Tin Shui Wai, and both zones 5 and 5A are only connected to Zone 4. Therefore, travelling between zones 5 and 5A is considered as travelling through three zones. Octopus cards Octopus card fares are calculated based on the minimum number of stops travelled (from origin to destination stops), rather than the number of fare zones travelled through. All stops have Octopus entry and exit processors at the entrances to and exits from platforms. Passengers may enter the system after scanning their Octopus card at an orange 'Entry Processor' reader. At this point, the maximum fare is deducted from the card. On completion of a journey, the card previously read by an 'Entry Processor' must be scanned at a dark-green 'Exit Processor', where the maximum fare less the fare incurred is refunded. Failure to do so within the time limit would cause the fare difference to be forfeited. If a person exits the same platform with the same card within 5 minutes, the fare deducted will be fully refunded. Light-blue 'Enquiry Processors' can also be found on most platforms. Like enquiry processors found in other places, passengers can check the balance on their card, along with the 10 most recent Octopus transactions. If a Personalised Octopus card is used, the number of Light Rail credits accumulated is also shown. Passengers using Personalised Octopus cards are able to participate in the Light Rail Bonus Scheme.
