>>1933905>>1929270Argentina is safe, it's a very developed country although poorly managed in certain aspects like shitty government officials. Overall it's got a strong economy but with a poor Gini coefficient meaning there is noticeable income inequality but actually it's on par with the USA. That means petty crime can be a bit high (just like in the USA) but it's minor shit like pickpockets and thieves in the big cities. It's not like Brazil or Mexico where it's a literal warzone or whatever.
The bars are actually just for protection against stuff like tree branches or other objects that may somehow hit the locomotive and incapacitate/injure the driver. It was common to see on freight engines in the USA in the 20th century, but as engines got larger and got windows made of really solid glass or similar, they became irrelevant. South American railroads still use a lot of old locomotives and rolling stock so they still have bars attached on a lot of them. I'm not sure if Argentina passenger trains have them or not, but safety bars are also common on those in places like India as it keeps passengers from possibly falling out (important when they regularly put too many people in a train).
