What's Inside

Four ways into the data

Search by cable number, symptom, panel code, or circuit -- the same way you'd look it up on the floor.

📡 Cable Index

Every cable's routing, connector pinouts, and manufacturer variants -- rendered from the real box-and-arrow diagrams, not guessed from flattened text.

755 entries indexed

🔧 Testing & Troubleshooting

Test procedures and monitor points with expected/trip values -- search by symptom, component, or test-point code.

89 rows, 610 source documents

📋 Panels

Panel checking charts for SB1, SB2, HB1, HB2 and F-panels -- terminal pairs, shorting links, and continuity data.

Who It's For

Built for the people doing the work

Railway Testing & Maintenance Staff

Look up a cable, panel, or fault symptom the way you'd search on the shop floor -- no need to page through a 357-page index by hand.

A purely voluntary individual purchase -- not procured or arranged by any Railway department.

OEM & Vendor Engineers

For ALSTOM, MEDHA, CGL, BHEL, ABB and SIEMENS field engineers who need fast, accurate reference data on-site.

A purely voluntary individual purchase -- not arranged by any OEM/vendor company or its management.
