tourists, monthly commuters). Elderly passengers are common, but wheelchair passengers are rare; not all stations are handicap accessible and not all rolling stock are level-boarding. Fare differentials between expresses and locals provide market differentiation. HSR ridership is observably more affluent, capturing many former airline passengers. Operating practices Operations on different railroads are variations of same general principles. TRA's practices are like JR's – somewhat labour-intensive, but immediate on-site accountability and close supervision contribute to high service quality, good delay-recovery capabilities, skills to execute complex maneuvers, and throughputs closer to theoretical line capacity than otherwise achievable. Stationmasters, train regulation, and dwell process Many TRA stations have "stationmaster duty offices." Stationmasters (their deputies, or platform staff) perform train regulation and signalling functions right from the platform, and provide train crew oversight. Two station crewmembers work busy locations, one per direction. They sound a whistle to warn waiting passengers of imminent arrivals. Passengers standing in yellow danger zones are asked to step back. As trains approach, they hand-signal drivers. Unreserved trains (without assigned cars) berth close to fare control, while expresses berth according to platform car markers, minimizing onboard baggage-carrying by passengers looking for assigned seats. Stationmasters may indirectly reduce overruns by providing immediate accountability. TRA's stationmasters and conductors jointly manage dwell time, like their counterparts at LIRR's Jamaica. Stationmasters regulate trains by enforcing correct train sequences and departure times; holding to time is actually a legal requirement. At transfer locations, they manage connections. About ½-minute prior to departure, stationmasters sound platform bells to signal impending departure. When trains are late, bell is given sooner, shortening dwell times. Once conductors close train doors, stationmasters give the "right away" using platform-mounted equipment. After departure, stationmasters remain on platforms, visually inspecting departing trains. Conductors as captains On board, conductors' primary responsibilities are not ticket examinations – station fare controls provide coverage. Instead, conductors operate doors and announcement systems, ensure onboard safety, sell onboard tickets, provide customer information and assistance, supervise onboard crews, perform emergency procedures, and troubleshoot equipment where possible. The position's multidisciplinary nature is reflected in Asian terms for "conductor" – (Mandarin lièchēzhǎng)/ (Cantonese ), or ; , still informally used on TRA) – which translates to "consist manager" or "train handler." They have overall responsibility for smooth onboard operations and customer experience, actively directing cleaners, attendants, even bento vendors. Onboard services On TRA expresses, cleaners periodically move through the train to remove trash,
