Just track upgrades should be enough for SRR-MAQ to be 130 kmph capable. EMD's and GOC toasters are already cleared for 130kmph operations. Electrification is not necessary for upgrading this route to 130kmph.
Is PGT SRR 130mps??? I can see trains run really fast in this stretch and do cover the dist in around 45 minutes though travel time allotted for almost all trains is more than 1 hour but never knew that it was 130mps. It would be good if some time can be reduced. I think to attain higher punctuality percentage, trains are given more running time
