Business Details
Daido Signal Co., Ltd. and its subsidiaries manufacture, sell, and install railway signaling safety equipment. Major customers include East Japan Railway Company and other railway operators. The segment consists of two pillars: system products such as Electronic Interlocking Systems / ATC Systems, and Field Products such as Track Circuit Devices / Centralized Monitoring Systems, and is the core business accounting for approximately 93% of consolidated net sales. A stable order environment has continued, supported by inbound demand and investment to renew aging equipment.
Recent Overview
Sales increased 17.8% due to growth in ATC and field products, with segment profit up sharply by 45.1%.
In the Railway Signaling Business for FY2026 (ending March 2026), an increase in system products such as ATC and Electronic Interlocking Systems and field products such as ATS resulted in sales of ¥23,958 million (up ¥3,615 million, or 17.8%, year on year) and segment profit of ¥3,735 million (up ¥1,161 million, or 45.1%, year on year). Orders received totaled ¥24,337 million (up ¥2,190 million, or 9.9%, year on year). The company also achieved its first SIL4 certification under IEC62279 for overseas markets, completed final operational verification of a virtualized PRC device, completed development of a radio-based railway crossing control device using GNSS, and secured its first contract for the Package Relay Interlocking System.
Key Products
Growth Drivers
- A stable order environment for railway operators' capital investment and maintenance/renewal expenditures, supported by steady railway passenger demand (continued inbound and leisure demand)
- Continued demand for renewal of aging equipment and ongoing capital and repair investment premised on stable transportation (maintaining a certain level within the railway industry)
- Growing investment needs for digitalization and labor-saving of railway facilities, including signaling and safety equipment
- Addressing labor-saving and workforce-reduction needs through the release of new products such as axle counters and compact digital time-element relays
- Development of new markets through advancement of the radio-based train control device for regional lines (field tests scheduled to begin June 2026)
- Expansion into overseas markets, leveraging the acquisition of IEC62279 SIL4 certification as a foothold
- Improved sales stability due to a significant increase in sales recognized under the percentage-of-completion method (goods transferred over a certain period), which rose to ¥10,147 million in FY2026 (ending March 2026), up 37.7% year on year
Risks
- Risk of fluctuations in raw material and energy prices (an uncertain procurement environment stemming from U.S. trade policy trends and the situation in the Middle East)
- Risk related to procurement of components, primarily semiconductors (requires continued monitoring)
- Risk of railway operators scaling back large-scale capital investment plans or reduced need for periodic renewal
- Risk of sales concentration with specific customers, including East Japan Railway Company
- Risk of labor shortages of engineers and construction personnel due to a declining working-age population
- For the FY2027 (ending March 2027) forecast, Railway Signaling Business sales are projected at ¥24,000 million (down approximately 1.7% year on year), a slight decrease, reflecting a risk of a gap between large-scale projects
