Nothing new sir, prior to LHBfication too this used to happen & cause of it is the excessive slack given by both the divisions of CR which are prior to Badnera & Nagpur division. This train can easily be speeded up by atleast 45 mins towards Howrah in CR & towards Mumbai same can be done by 45 mins before Igatpuri, hence ultimately reaching Mumbai CSMT by 22:30 Hrs.
