Hi, If possible please convert ICF coaches from train number 12659/12660 Nagarcovil- Shalimar Gurudev SF Express to the New LHB coaches. It is a single train that has over 35 stops & covers a distance of 2508km (Duration:4 h 35min). It is also one of the longest-running trains in India. Several other longest-running trains such as Vivek Express(Train no: 15905/15906), Kerala SF Express(12625/12626), etc have been fully integrated with the new LHB Coaches.
