JTJ express has only twelve coaches sir. We can increase to 15 or even 20 , then the problem will be solved. The problem is with the RSA. SBC-JTJ express RSA part should be reworked and it can be delinked from then RSA chain . Else it can have RSA with Yelagiri express. At 8:45 , it can go to Dharmapuri as a normal express ( even DPJ does not have any train after Karaikkal passenger till 16 hrs). It can reach DPJ at 11:45 hrs. 12:45 from DPJ return 15:45 to SBC. Then it can proceed to JTJ and next day it can go to MAS where is can have maintenance .
