Yes I am from Rajasthan but I have lived in Manipal are for more than 2 years.
Maybe I dont know a lot but by looking at the latest IR Map, I can see that if a train goes to Coimbatore(CBE) from Podanur which is just 6Kms, it has to come back to the main line.
I dont know that but there might be a provision of a sharp turn to let the train get back in the main route, without changing the direction of the engine, but still it will...
more... involve a lot of time.
So I was advocating a stop at Podanur, instead of travelling upto CBE.
Mr. shanavas adviced it to travel to Coimbatore North, but then how will the train come back to its main route without reversing.
Please see this latest route map of the IR
