Here is what J. R. R. Tolkien wrote in “Leaf by Niggle” (just before, Niggle was only told to take the train that he finds on the railway station nearby, he had no information on where he should go):
He [Niggle] walked downhill to the station briskly, but without hurry. The Porter spotted him at once.
"This way!" he said, and led Niggle to a bay, in which there was a very pleasant little local train standing: one coach, and a small engine […]. The coach was empty.
"Where does this train go, Porter?" asked Niggle.
"I don't think they have fixed its name yet," said the Porter. "But you'll find it all right." He shut the door.
The train moved off at once.
What does the bolded part mean? “You'll have no problem finding the place” or “you'll think the place is all right”? I think the verb “find” means both, but I don't believe that Tolkien was so ambiguous. Or should I?
That Niggle had no problem finding the unknown place is obvious: a little bit later in the story, the train just stopped when it arrived at its destination, and so Niggle went out to, as it turned out, his magical country. But maybe the Porter liked telling obvious things, or maybe the thing was not so obvious to Niggle yet, so I can't decide…
