DMU Glodelania Express and changes on Tantan Express

Glodelania Express V2 will make a comeback but it will be a DMU or Diesel Multiple Unit train but some people argue that they want to train into be 3rd rail, but this mean they require the 3rd rail track pack which was downloaded few weeks ago. With Glodelania Express V2 no longer a pantograph train, the pantograph car will be removed. Tantan Express will have the same treatment through an update. With this in mind, Glodelania Railway  may no longer needed to construct overhead wires, allowing for Glodelania Railway to focus on simplicity for lightweight handling on low end devices like Gamma and Delta. Some people asked, why not convert the current Glodelania Express. The thing is, the train model used in Glodelania Express V2 is a generic East Japan commuter train and not exactly resemblance to E231 Series as previously thought before, while the current Glodelania Express is reassembled E231-1000 Series which is not a fictional train model. So modification on the train addon is not ideal.
