If it is unsafe, does that mean that a "Spanish solution" is only used in backwards, uncivilized countries that do not respect passenger safety/
Kinda. Many newer metro's either have platform doors (prevents access to track level) or are overhead based.
Even Line 1 in Barcelona, the first to have stations with triple platforms, has an overhead power supply (rigid rail like in the 509 tunnel, not catenary).
A Spanish solution with passenger accessible 3rd rails is a somewhat unusual situation in new metro line.
I think if you do the math, it would be worth adding platform doors.
