They might have to change the name of their company since they will not only make air brakes once they achieve success
The comments meant a subsidiary. One company cannot deal with all industries. It will then become large, it is better to create a main office and divide the subsidiaries from there. General Motors office, a Cadillac,hummer manufacturer
