Budget allocation to Tamil Nadu for railways has increased more than eight and a half times since 2014, reaching Rs 76.11 billion (Rs 76,110 mn) for 2026–27, the Union Minister for Railways said in posts on X. The allocation marks a significant rise in central spending aimed at expanding rail infrastructure across the State. The minister noted that the increase reflects planned investments in new lines, capacity enhancement and station redevelopment.

For ongoing projects only 24 per cent of required land has been handed over, amounting to 1,052 hectares out of 4,326 hectares, and Rs 14.65 bn has already been paid to the Tamil Nadu Government for land acquisition. Several critical projects are delayed due to pending land acquisition with the State Government. The ministry reported that persistent land issues are restricting timely implementation despite available funds.

Land acquisition remains particularly acute on the Madurai–Tuticorin new line via Aruppukkotai where 91 per cent of land remains to be acquired and on the Tindivanam–Gingee–Tiruvannamalai new line where 86 per cent is pending. The foundation stone for the Rameswaram–Dhanushkodi new line project was laid in 2019 but land acquisition has not yet begun. The Centre has nevertheless sanctioned multiple new lines, doublings and third and fourth lines, and detailed project reports have been prepared for further capacity expansion to support the State's economic and industrial growth.

A total of 77 Amrit stations have been identified for complete redevelopment in Tamil Nadu, with work completed at 18 stations so far. Since 2014 approximately 1,350 km of track has been constructed and Indian Railways in the State has achieved 97 per cent electrification, equating to 2,386 km of rail lines electrified during the period. Modern trains built under national manufacturing schemes are operating to improve affordable travel, with nine pairs each of Vande Bharat Express and Amrit Bharat Express services currently running. Officials indicated that these measures are intended to enhance connectivity and support regional mobility.
