Forward Linkage:- Forward linkage is create when investment in a particular project encourage investment in subsequent stage of production.

Similarly,  

In Railroad:- Railways help in transportation of goods and raw material from different industry. Therefore almost all industry would get benefit from it. Railway also help the tourist in travelling.
