No direct train from Zhaoqing to Guilin. It is 800km from each other. If you want to travel by train, you can get to Guangzhou from Zhaoqing first. There are two trains every day from Guangzhou to GUilin, all tourist special lines. Or you can take bus at ZHapqing Bus Terminal at 17 Duanzhou 4th Road. Two buses a day, one in the morning and one in afternoon. For the departure time, you should make sure to the bus station. You can book the bus bus ticket in advance. It takes about 12.5 hours by bus. I think train is a comfortable way.
