ji Bahoot saare reasons reasons hai iske piche, Except chord line most of segments of ECR have 52 kg sleepers than don't support high speed operations, Poor maintenance of tracks, Dense population around tracks which leads to PSRs, Majority of sections of ECR still depends on human Hands for even changing the tracks of trains. Ab batao aap ki aise infrastructure me koi train kaisi jyada Average speed degi? Railway ECR me development k liye fund nahi deta hai to bina investment result kaise milega. Aap ECR k kisi A1 category station ko utha lo Except Patna or uska comparison kisi or zone k B category k station se kerenge to wo B category ka station ECR k A1 category se jyada developed milega aapko.
