I am a native of Jabalpur. What you said is correct. Ironically, this train is now a better option for JBP folks due to more convenient timing. Earlier it departed from JBP at 6 am and return arrival was 11.30 pm. I use a combination of this and 12001/12002 to travel to Delhi when flights are expensive and Gondwana / MPSK are in waiting (2AC waiting does not confirm easily for both).
