Southern Railway — Avoidable inconvenience

I am Dr P.P. Venugopalan, 70 years old and my wife 63 yrs old resched Shornur railway station on 27th october to board Garib Rath Express 12202, .The train was late for more than 45 minutes and the local authorities were not able to inform the concerned passengers where the train would enter- I mean the platform number. Webeing, senior citizens need more time to reach the allocated platform.On enquiry, the porters and vendors, taking pity on us told the train may come to any ofthese platforms- 4, 5, 6 or7 . We were then waiting on the overbridge at a strategic location to reach to any of these platform numbers when the divine announcement is heard.
Our coach no was J2 and our attempts to find out the coach location also failed, as none could give us the exact location.The train streamed in and we were more or less placed in the mid location of the platform and we saw J1 immediately after the engine and presuming J2 as the next coach, we lifted our bags and started running to J2 but then to our surprise, we found the coach that folllowed J 1 was G 1 and then folowed G 2 to G 10. As the train started moving by then, we asked the fellow passengers there who revealed that J 2 Coach was at the terminal end of the train, then we both started carrying our bags and walking through all G serial coaches to reach J2 coach, which took us about 15-20 mts. of hard toiling to keep our balances steady.And the AC Chair car coach J 2 was in two divided parts and with hardly any space to even sit properly.( it was a much smaller chair car coach)
Somehow we got into our seats and cursed our fate and " congratulated" railways for their brilliant idea of seperating J1 and 2 COACHES wide apart with 10 G coaches in between.
Even the rail authorities at the station fail to inform the exact platform number, how does the 139 magic number supposed to give us the platform number etc.?
Will remain grateful if the authorities could apply common logic instead of an unnatural logic in placing the coaches in a haphazard fashion and also ensure that the coaches positioned are travel worthy, so that the minimum comfort is provided to the passengers.
