1) Snapshot

• Why Howrah is iconic:
  Howrah, known as the “Sheffield of the East,” is one of India’s oldest engineering and foundry clusters, with roots tracing back to the British colonial era.
  It is home to over 1,000 foundries and hundreds of engineering units, specializing in grey iron, steel, and non-ferrous castings, rail and wagon components, pump parts, and heavy industrial machinery.
  Howrah played a critical role in supplying India’s railways, jute, textile, and heavy industries, and continues to serve as an important MSME-driven manufacturing hub for eastern India and export markets.
  
• Global Positioning:
  The cluster supplies to railway networks (Indian Railways, Metro Rail projects), industrial equipment makers, and exporters catering to Europe, Africa, and Southeast Asia.
