Inner fastening brake disk (Series N700)

・ Reduces the extent of disk deformation caused by friction heat when brakes are operated and also obtains higher frictional force

・ Shortened stopping distance in overhead-line failure (caused by earthquakes, etc.) by improving deceleration

■Employing the central fastening brake disc to shorten braking distance

- The use of dedicated tracks exclusively for high-speed passenger rail service

- A fail-safe, reliable, proven Automatic Train Control

(ATC)

Concept of Crash Avoidance on a dedicated track is characterized by two key cornerstones:

Crash Avoidance Concept

©

Shinkansen

- Complete separation from: •  Freight traffic (pulled by heavy locomotives with lower braking performance)

•  Lower speed passenger traffic (poor running performance)

•  Road traffic

Road Traffic

Zero possibility of catastrophic collision with freight, lower speed passenger and road traffic

- Eliminates possibility of collision with the preceding train - 100% safety record in Japan for over 50 years

Software - Kaizen in action Background:

• Mechanical door requires constant maintenance including washing mechanical parts

• Washing oil costs tens of millions of yen

Before:

• Replacement cycle of the washing oil varied by staff

• Staff changed the washing oil when the colour looked ugly

Analysis:

• Dirty oil still has ability to clean the mechanism.

• Impurities are needed to be removed

Critical issue for reliable, safe operation if the door does not open/close as operated

©

Software - Kaizen in action

New method:

• Reuse the washing oil

• Introduce foreign matter separator

After:

• Cost saved

• Washing quality is more standardised

More reliable, safe rail services with less costs

Software - how can we develop it?

Software - culture moulding

• The processes, values and assumptions developed by a group over time, that is then passed on to new members of the group

• How is culture moulded?

1.  Primary: Management behaviour; resources and awards; promotions

2.  Secondary: Organisational structures; design; ceremonies, rituals and stories; formal mission and value statements

3 Safety requires absolute confirmation and thorough communication.

4 Safety requires cooperation as one beyond assigned tasks.

5 When in doubt, take the action deemed safest and ensure that nothing is missed.

1　Safety is the number one priority of our transportation service.

2　Safety starts with strict adherence to rules and fulfillment of duties, and rests on continual self improvement.

Keep sending the safety-1st message everywhere
