Diesel Locomotives on the Indian Railways started in late 50s, with the import of locomotives from M/s. ALCO, USA. With the setting up of Diesel Locomotive Works at Varanasi in the year 1961, the addition to the Diesel Locomotive fleet started at a regular pace. In the earlier years of diesel operation, a limited demand of spares was met by Diesel Locomotive Works, Varanasi mainly through import, but the demand increased with the increasing size and age of the fleet. It was in the context of the need for high precision components for maintenance support to the diesel fleet, that in the year 1979, a decision was taken to set up Diesel Component Works at Patiala. The Foundation Stone of Diesel Component Works (DCW), Patiala was laid on October 24, 1981 and production started in 1986. A decision was also taken that DCW will do midlife Rebuilding of Diesel Locomotives after a service life of 18 years. Accordingly, Phase-II of the project was sanctioned and the work of Rebuilding started in 1989. The name of DCW was changed to Diesel Loco Modernisation Works (DMW) to signify the modernisation of Diesel Locomotives being done in the unit DMW started manufacturing new WDM3D 3300 HP ALCO Locomotives in 2010-11 and turned out 227 WDM3D locomotives till 2015-16. First 3-Phase IGBT based 6000 HP WAP7 Electric Loco, First Diesel Electric Tower Car (DETC) & First 6FRA 6068 Traction Motor produced in-house in Dec’18. DMW is also manufacturing Multi Genset Locos (fuel saver of 15-20%) till date.
Here’s the most reliable and updated information on the Diesel Loco Modernisation Works (DMW) Pink Book, now reorganized under India’s railway budgeting system:
📚 What Was the Pink Book?
The Pink Book was Indian Railways’ annual budget document detailing capital and modernisation projects costing over ₹2.5 crore. It listed sanctioned works by zone and production unit, including specific allocations for each project.〔turn0search10turn0search3〕
🔧 Diesel Loco Modernisation Works (DMW) & Its Pink Book
- DMW (Diesel Loco Modernisation Works), Patiala, formerly Diesel Component Works, is responsible for mid-life rebuilding of diesel locomotives, manufacturing ALCO and WDM/WAP series until recent electrification projects.〔turn0search0turn0search16turn0search14〕
- The DMW Pink Book once listed capital projects—diesel loco rebuilds, new ALCO locos, control systems, simulators, etc.—that DMW would execute.〔turn0search0turn0search5turn0search16〕
🚫 Discontinuation & Transition in 2025
- As of April 2025, the Railway Ministry has officially discontinued the central Pink Book, moving to zone- and production-unit–wise budget documents.〔turn0search1turn0search2turn0search3〕
- This means the traditional DMW Pink Book will no longer be published as a standalone document. Instead, the Consolidated Budget Statement or equivalent unit-specific reports now cover all DMW modernisation works including those formerly listed in the Pink Book.〔turn0search1turn0search3〕
⚙️ Sample Projects Previously Listed for DMW
From past editions (e.g. FY 2018–19 Pink Book & related releases):
- LCAVR (Loco Cab Audio‑Video Recording System) outfitted on diesel locos for accident investigation.
- Distributed Power Control System (DPCS) fitted on high horsepower diesel locos to improve hauling efficiency and reduce crew.
- Provision for simulators, crew rest-room modernization, and maintenance shed upgrades.〔turn0search5turn0search7〕
🧾 At-a-Glance Comparison
| Item | Before 2025 | From FY 2025–26 Onwards |
|---|---|---|
| Document Name | DMW Pink Book (standalone booklet) | Part of Production-Unit/Zone-wise Budget Documents |
| Includes | Capital projects > ₹2.5 Cr at DMW | Same projects under DMW section in CBS for FY2025–26 |
| Projects included | Diesel loco rebuilds, safety systems, tech upgrades | Same, listed under DMW’s allocated works and budget |
| Publication Time | Soon after Union Budget | After zone/unit budget documents released |
✅ What To Do Next?
- Visit the Indian Railways Railway Board or DMW/Patiala official website. The Consolidated Budget or CBS document for FY 2025–26 should list DMW’s capital works and modernization agenda.
- If you’re interested in specific projects (e.g. simulator installations, LCAVR upgrades, ALCO rebuilds or genset locomotives), these will now appear in DMW’s share of the CBS or equivalent.
🧠 Final Thoughts
- The DMW Pink Book no longer exists as a separate publication but its contents are preserved—now embedded within broader unit-specific budget documents.
- Modernisation works by DMW remain ongoing through these projects—particularly as Indian Railways phases out diesel by electrifying lines and converting diesel fleet into WAG‑11 electric models.〔turn0search19turn0reddit18turn0reddit26turn0reddit27〕
- For current project updates, consult the Production Unit budgets issued for FY 2025–26 when they’re released.
