Students' learning motivation and gains in the professional training are essential criteria for evaluating the vocational teaching level. This study designed the virtual reality guidance (VRG) system to teach the skills of urban railway vehicle overhaul. The VRG system aims to improve students' enthusiasm and gains from learning. The system has two modules, teaching and experiment modules, respectively. The teaching module added the independent design mode and evaluation mode to guide students to participate in and enjoy the teaching system actively. The experiment randomly divided 80 urban railway vehicle engineering students into the experimental and control groups. Participants underwent the entire pretest, teaching, and posttest process. The results show that the VRG system endows students with more effective operational skills learning rather than traditional teaching methods. Also, the novel system can guide students to discover their professional advantages and enhance their enthusiasm for professional learning.
