The Southbound red head ktt Through Train T827 (GuangZhou to Kowloon)

[Trainbrain1949]

The locomotives appear to have a cab at each end. What is the reason one is painter red?

[righk]

Yes you are right.

No any meaning of the painter red and white. The double red head was used usually. But sometime they use the single head, or white. In Switzerland, this locomotives is Re465, they use one locomotive only, the other side was a driving trailer.
