I thought it was Buddhists who laid the railroads.
Chinese on the West of the Rockies, Irish East and through the Rockies, meeting in Utah.
No muzzlemen stopping work five times a day to howl toward the East.
The ONLY moslem I can find, Haji Ali(Hy Jolly), was brought in on the orders of Jeff Davis, secretary of war, to work with camels, in the American west in the 1850s camel experiment at Fort Davis TX.
It was a success, but abandoned during the Civil War when Jeff Davis went on to a more important job as President of the Confederate States.
