Which school is better for Lanzhou to learn rail transit?

I think the best is Gansu Eastern Airlines High-speed Railway School, and there is another school called Gansu Oriental Industrial Technical Secondary School, which also has a railway major. These two schools are the best schools I have known in Lanzhou for decades, and the local reputation is quite good. The children of relatives went to Gansu Eastern Airlines High Speed Rail School, and now they have graduated. Their school has been directly assigned to them, in the Urumqi railway section.
