KTX High Speed Train South Korea Case Study

STUDOR CONTRIBUTES TO PASSENGER COMFORT

The Studor Trap-Vent was specified by KORAIL for installation in their KTX-Sancheon high speed trains as part of their overall strategy to ensure maximum passenger comfort by reducing all operating noises.

Background

When KORAIL launched the KTX-Sancheon high speed train on 2 March 2010 ensuring passenger comfort was one of their top priorities. Other considerations were speed, safety and overall impact on the environment. The state-of-the-art KTX-Sancheon is built with Korean technologies, and its introduction has provided a travel time to anywhere in South Korea of less than 3 hours.

The aeorodynamic KTX-Sancheon has a top operational speed of 305km per hour. It takes only just over 5 minutes to reach this speed and can stop in just over 3,300m at this speed in an emergency. Both the trains and the tracks have been designed to run as quietly as possible – for the benefit of the passengers, as well as the environment the trains pass through.

Product Selection

All aspects of the previous high speed train design were analysed and areas for improved passenger comfort were identified – this included reducing down the overall size of the train from 20 cars carrying 127 first class and 808 standard class passengers, to 10 cars carrying 30 first class and 333 standard class passengers, and extending rotating seats to all classes of passengers travelling on the KTX-Sancheon.

High speed trains have a number of challenges due to their speed, which is why state-of-the-art technologies are key to address these challenges. Even on trains there is a drainage system for the toilet facilities, and this was an area where it was identified that passenger comfort could be improved – by initially installing the Studor Combi-Siphon Plus, and later its successor, the Studor Trap-Vent on wash basins throughout the trains.

The Studor Trap-Vent is a combined 50mm water trap with integral Air Admittance Valve (AAV). The AAV function protects the water trap seal by allowing sufficient air to enter the drainage system to enable the water to discharge efficiently and quietly, whilst ensuring that nasty smells and potentially dangerous gases from the drainage system don’t enter the living space. 

Result

The Studor Trap-Vent (and its predecessor the Studor Combi-Siphon Plus) has been successfully installed throughout the KTX-Sancheon high speed trains, eliminating unpleasant and noisy gurgling sounds from the toilet facilities – contributing to the overall comfort, health and well-being of the high speed train passengers.
