There are two issues with casing a 571 movement, first is Elgin's odd use of a detent stem in an otherwise rugged Railroad Watch, very few if any other 16-size railroad movements went with that kind of system. Secondly, the 571 as you'll see in the image below this posting had to be provided with a crescent-shaped cut-out area in order to provide sufficient space for regulating the movement when cased. I wonder what they were thinking when coming up with that design!
It would probably be far less bother to keep on a lookout for a suitable case, there were even some Star replacement cases made especially to fit an Elgin Grade 571 movement, You might place a free to our members IHC Wanted Ad.

You would be ok using a 572 or 573 case since the 571,572, and 573 share many of the same parts, even the cases, as a side note the case from a grade 616 can also be used. These were 21, 19 and 17 jewel versions of the same movement type (lever set) the 574 and 575 were both pendant sets. As Lindell mentioned you will see a factory made cut-out area on all three of the movements I mentioned so that you could get to the regulator screw, which is a bit odd since on the 47X series the screw was facing the opposite direction. Below is the grade 506 which used the normal stem configuration that nearly all prior Elgins used and it also shows the regulator screw on the opposite side, which the 47X grades also had.
