Before we go where nobody else is going, we must think about a few things first. Most importantly, how to identify (and avoid) potential noise factors.
A word of caution, though: (Thanks to Gordon Hempton for your thoughts)
There are often very good reasons why no one else visits certain places!
Whether you're in the city or in nature, there are dangers everywhere: mine fields, tigers, quicksand, man-eating plants [ add your own nightmare scenario ].
If you want to have a lasting career as a field recordist, you need to be aware of the many possible dangers lurking out there. Ultimately it is up to you how far you want to venture into the dragon's lair. But if you've seen the film The Revenant, for example, you will know the consequences of running into a bear in the wild...
About the audio file: the perfect cargo train sound without background interference (or bears). Please note that there are no sound issues at all as the train arrives/departs. This recording was not polished in any way (e.g. noise reduction or similar tools). Why can't it always be like this?
