For Chennai and SOLAPUR u have daily connectivity. For Banglore u have biweekly connectivity. You have extremely good connectivity wid NGP which one of the major hub coz of diamond crossing. Even if new trains are introduced from AK majority of them will travel via NGP. Lastly AKOLA is not that big city. There are many cities who deserves lot more rail infra.
Still all the best to Akola people ; u guys have some good political leaders ; may be they can help u to grab new trains in rail budget 2014
