MAS-GDR
MAS/Arakonam-JTJ
MAS-Renigunta
These are the only sections in SR planned for 130 KMPH upgrade. All the time they do is run some inspection special @ 130 KMPH every 3-6 months and don't get approval.
Other...
more... sections in SR are not approved by IR to increase speed beyond 110 KMPH.
MS-DG section may get upgraded to 130 KMPH hopefully in next decade.
