i hv been using this site since a number of years and it has been exceptional. i cud bank on it for all railway related info. Suddenly , it seems a new update IRI 4. has been launched which has made the earlier version redundant. i am a senior citizen of old school and am finding the updating process very cumbersome. wud someone help me get over this difficulty ? or, cudnt the earlier version b effective simultaneously.
thanks in anticipation.
