8. We ended up on the 11th floor and yes, faced railroad tracks, but slept soundly at night & expect some noise while staying in any downtown hotel (chicago area hotels much worse with sirens, etc); hotel is within walking distance of many museums (6th Floor Museum, the great Dallas Aquariam, the West End restaurant area); and when we got tired from walking, can walk underground to Union Station & for $4.00 for a day pass, could take the DART system trains anywhere.
