interior of a train carriage

interior of a train carriage. The carriage is brightly lit with white overhead fluorescent lights. The walls of the carriage are white with yellow handrails and yellow support beams. The carriage is sparsely populated, with only a few passengers seated on the green-and-black patterned seats. The passengers are all wearing dark clothing. The carriage is clean and appears to be well-maintained. There is a sign on the wall to the right of the image that reads "Hold on. The tram may stop suddenly". The sign is yellow and has a black background. The image is taken from inside the carriage, looking towards the front of the train. The image is slightly out of focus and blurry. The image was taken on a train in Melbourne, Australia, at the coordinates -37.829, 144.955, which corresponds to the Southbank area of Melbourne.
