等作者我再改改内六接入沪昆这一段的问题

通过添加虚拟站台实现内六与沪昆相连的上下行问题。Implementing the up and down connection between Neiliu and Shanghai Kunming by adding virtual platforms.

本次还原了内六铁路在沪昆段上下行的实况。This time, the actual situation of the Neiliu Railway running up and down the Shanghai Kunming section has been restored.

本次缩短“六盘水站”的站台长度，优化路线时间，减少自动化带来的晚点信息。This time, the platform length of "Liupanshui Station" will be shortened, the route time will be optimized, and the delay information caused by automation will be reduced.
