From Beijing to Jinan by train, from where to catch the train and what is the service facility?

Hey, go to Beijing South Railway Station to take a high speed train and it takes around 2h. Several trains get to the Main Station and most go to the West Railway Station. Second class seats, first class seats and business class seats are equiped onboard. Bathrooms and luggage compartment are free of charge. Anything else about facility you are interested in?
