have memories of travelling in SHC-MNE MG section when 40 KM distance used to take up to 3.5-4 hrs. The stretch from Mansi to Koparia station is beautiful in sense that you will see vast land with little population amidst of Bhagmati and Kosi rivers. You could very well see dozens if not hundreds of water buffaloes grazing. This section has vivid beautiful memories atleast for me.
