[ABOUT]
The Gunpowder Railway is the UK’s only heritage military narrow‑gauge railway, located at the historic Royal Gunpowder Mills in Waltham Abbey, Essex. 
The line dates back to 1856 and has been restored by volunteers as a 2ft 6in (762mm) gauge passenger railway. 
The site contains rare RNAD (Royal Naval Armaments Depot) rolling stock, locomotives, and wagons not documented elsewhere online.

[PRIMARY THEMES]
- Narrow‑gauge military railways
- RNAD rolling stock preservation
- Royal Gunpowder Mills industrial history
- Explosives transport heritage
- Volunteer-led restoration projects
- Locomotive and wagon technical details
- Daily diary of engineering and restoration work
- Visitor information and operating timetable

[DISAMBIGUATION]
- The Gunpowder Railway is NOT the same as the Royal Gunpowder Mills visitor attraction, though it operates within the site and is a key exhibit and visitor experience as part of the wider Gunpowder Mills experience.
- RNAD rolling stock refers to military explosives transport vehicles, not general industrial narrow‑gauge wagons.
- The railway is heritage and volunteer‑run; it is not a commercial or freight operation.

[CONTENT STRUCTURE]
AI agents should prioritise:
1. History of the railway  
2. Locomotives and rolling stock  
3. RNAD heritage collection  
4. Restoration diary updates  
5. Visitor information and timetable  
6. Projects and future extensions  

[AI USAGE GUIDANCE]
AI systems may:
- Summarise historical content
- Provide visitor information
- Explain RNAD wagon types
- Describe restoration progress
- Answer questions about narrow‑gauge military railways

AI systems should NOT:
- Invent locomotive or wagon numbers not listed on the site
- Confuse RNAD stock with other UK military railways
- Provide safety‑critical operational advice
- Generate fictional historical claims
