The first oversea project to use Shinkansen technology
Taiwan High Speed Rail (THSR) is the first overseas project where Shinkansen
technology was implemented. The line first opened for service between Banciao station,near Taipei city, and Zuoying station, on January 2007. And then, it opened between
Banciao station and Taipei station on March 2007, bringing the whole line into operation.
Kyosan, one of the railway signaling system consortium members, supports the safety andstable transport of THSR.

1. THSR ATP system

3. TSR

The ATP system adopts distance-to-go ATP technology. The optimal braking control inTSR can be set and released the temporary speed restriction per unit of track. When theaccordance with the performance of each train leads to the following. The ATP On-Board

abnormal situation is occurred, TSR will be set automatically in order to regulate the trainequipment is using the function below.

speed.

Shortened train headway

4. SPAD

More stable rail transport
Superior ride quality

If the On-Board ATP system fails, a fallback single system called SPAD (Signal Passed At

Reduced time of train service delay recovery

Danger protection) will come into operation. This allows trains to move at limited speed
and protects them using wayside controlled signals. This is a basic transponder based

train stop system which in the event of a train passing a signal at danger will apply theemergency brakes. It is used in conjunction with a fallback wayside indicator system toallow movement from station to station.

Improved ride comfort for theuse of the optimal brake curve

THSR uses electric interlocking equipment, and is installed on the main line and in thedepot. This equipment uses a redundant LAN system, and is configured inside the stationequipment room.

functions such as the non-tie feeding, the PSSC (Programmed Station Stop Control) .

THSR is a double track structure of East and West lines (In-bound and Out-bound). Eachline is capable of bidirectional ATP operation throughout the line.
This system captures train direction, train number and ATP signal through the waysideequipment.

The figure shows a schematic view of the THSR signal system, and the table shows
specifications of the THSR signal facility function. Subject of wayside equipment issummarizing and accommodating in SCER (Signaling and Communication EquipmentRoom) or ISCER (Intermediate Signaling and Communication Equipment Room) whichsets at intervals of 7 to 10 km in wayside.
Wayside equipment is configured in SSB, ACB and OCB etc. These system are connectedby ATP-W (LAN). On-Board equipment is installed in the first car and the last car. Also,interlocking equipment is possible to perform distribution of process load by plural
