I believe the answer is
The riddle was tricky (as indicated by the title) and each of the lines is
Left alone, I'm a word with five letters.
I'm honest and fair I'll admit
Rearranged, I'm of no use to trains.
Again, and I'm an overt place, warm and well-lit.
I could be way off track but I have a good feeling that this is it.

I absolutely loved this puzzle! It hit the exact blend of "curse you" and "a-ha!" moments to make for a really enjoyable time. I sincerely admire the ...

I think the answer to the riddle is:
Look for the infix, odious indeed,
Obscenities and evil, a hex, but no e.
Oddly the suffix, denotes with just three,
Prefixed by back, again, it is ?
As for the title:
I know this isn't it, but I got on this train of though and couldn't get off. Not a real guess but I had fun with it
Do exactly what I tell you.
Ask me if you see the moon.
That, over there; pick it up.
State your name, for the record.
Mentor me in simple English.
Add two more, then report back to me.
Find a nervous man, then tell him this:...
This is vastly different from my existing answer, so I'll add it in another one. I'm pretty sure this is it. Heavy thanks to @LordFarquaad for finding a LOT of this (and they deserve the bounty:)
As already confirmed:
Go to the bottom you'll see:
Rounded but right there with me:
Every morning, each open warning:
Negating the color you see:
I think the answer is
Jasmin, or juniper, the suffix is one.
Obscured and unseen, until we are done.
Next is the prefix, for summer's flowers.
Exactly; eight chunks, of ninety-three hours.
Summer the best time, in fact, just July; together made history, a season in time.
This feels a bit underdetermined to me, probably meaning that I'm missing some hidden hints that nail things down further. But here's one thing we can do, which meets the explicitly given requirements:
where we take
My guess is
Sneak in the prefix, while hunting for boar; beware of bobcats, their swift silent roar.
Ask for the infix, obviously straight; oh, no that’s a lie, oh well, too late.
Indeed yes the suffix, similar to here; maybe that was the lie, in that is my fear.
And the acrostic
I'm not sure about the future and time aspect of it, though.
Some parts of this may be a bit stretched, but hopefully it's close enough to the solution.

I have 2 possible answers. But let me try this one first.
Is it perhaps
Looking for an exit? You won't escape that easily,
Overwhelmed with hexes, I'll make you shift uneasily,
So many questions, but so little time,
Too few suggestions, forbidden to climb.
Perhaps you follow the old adage, to have one hand always on me.
A foolish attempt, useless baggage, you can never trust what you see.
Take heed to be ...
I believe the answer is:
Some work is done here which is really just my though process so forgive the lack of structure:
My suffix is my prefix, defined for both as well;
My infix has one anagram, its colored yellow, and smells.
After the final hint:
Explanation of hint one:
What does the http and https stand for in a web address?
What is the internet protocol suite called?
What important piece of hardware began mass production in 1958?
What protocol replaced DIXIE and DAS in 1993?
Which would give:
