A platform extension is clearly visible at the south end of the platform, where the name tablets and "A" are authentic replicas on the northbound platform wall, while the southbound wall was tiled around them. The area on the southbound wall where the platform extends out is made of replicas as well. Since there were no mosaics built, only a green wall was present prior to renovation, which indicates where the platform was extended in the 1964–1965 to fit ten car trains.
