Chennai Central to Chennai Central in 13 hours
I was just going through the MEMU rakes in Chennai when I saw this RSA
66015 MAS TPTY MEMU 7:15AM->11:10AM
66033 TPTY NLR MEMU 11:25AM->14:50hrs
66036...
more... NLR MAS MEMU 16:00hrs-> 20:35hrs
surpirsingly in alternate direction also it follows almost same timings
66035 MAS NLR MEMU 07:45AM->12:20hrs
66034 NLR TPTY MEMU 12:30hrs->15:55hrs
66014 TPTY-MAS MEMU 16:10hrs-20:35hrs
1st time seeing a RSA in circular form and that too with almost same timings followed by both rakes-incidentally in morning both rakes follow each other from AVD shed to MAS and same in return too in evening!!
