Pass" (), which had been offered since 1998. The Round-the Island Pass had several restrictions making it unpopular. First, holders of the pass must either travel in the clockwise or anti-clockwise direction without traveling backwards. Secondly, travelers could only pick seven stops to get off and visit. Once a traveler has got off in seven stations, the pass became invalid. These restrictions were deemed too restrictive and limited the use of the pass. After the issue of TR General Pass in 2010, this pass ceased to be issued. Passenger information systems and signage TRA takes a holistic and comprehensive approach towards passenger information. Devices used (in both English and Chinese) range from schedule posters, fixed signage to departure monitors and next-train displays. Split-flap display boards, monitors, or smaller LED displays are provided at major terminals and principal stations. One display per control area shows boarding times and track assignments. Delays as short as one minute are posted. Large acrylic signboards show departure times and fares at smaller stations. Ubiquitous clocks throughout stations and facilities make it difficult to find spots where fewer than two clocks are immediately visible. Platform signage, next train identifiers Backlit acrylic signs (airport-style with iconic representations) identify platform and carriage numbers, and provide directions to facilities like restrooms and elevators. Boxes display schedules, tourist information, and service change notices. Large signs (legible from passing trains) indicate station names, and distances to previous/next stations, for use by passengers and crew. Platform LED displays provide next train identity, departure time, delay information, and context-sensitive messages, including public service announcements. Onboard displays and announcements TRA's mixed fleet ranges from 1960s hauled stock to new Tarokos and commuter trains. Newer trains feature automated display/announcement systems with high-density dot-matrix LEDs like Taipei's metro. On long-distance coaches with longer time between station stops, scrolling displays are used. Like in Continental Europe, automated onboard announcements are multilingual. Announcements are in four major languages (Mandarin, Taiwanese, Hakka, and English). In rural areas, announcements are also made in local aboriginal languages; Taitung line has the aboriginal Pangcah/Amis language. In unusual situations, conductors can usually make announcements in at least two languages. Trains lacking automatic train location features are not simple to retrofit. TRA devised low-cost multi-lingual "announcement boxes" connected to the public address system, manually triggered by conductors on approach to stations. Exterior train identification Identifying arriving trains quickly and accurately is equally important to
