Couldn't find any old threads dedicated to Arlington Stadium, so I figured I would start one with the photos that I have.
First photo is of the original Turnpike Stadium in 1969, capacity of 10,000.
They were trying to watch costs so much when the stadium was expanded for the 1972 arrival of the Rangers that they built a massive bleacher section with 16,000 seats, almost half of the stadium's 35,000 capacity. As a result, the stadium looked very disjointed to me whenever I watched Yankees - Rangers games on TV. Upper Deck was added later in 1978 bringing capacity up to 41,097. Many publications and sites say the Upper Deck expansion was in 1979, but the Rangers drew crowds of 37-40,000 in 1978 including 40,078 against the Yankees on Opening Day.
First photo is of the original Turnpike Stadium in 1969, capacity of 10,000. You can see the seating set-up was like the cookie cutters (Shea, Busch II, etc.) with the circular second level surrounding the field level seats. Stadium was expanded in 1970 to seat 20,000.
Second photo is during 1971 when the stadium was under construction for the expansion.
Third photo is a packed house during the 1970's before the 1978 Upper Deck. Notice the signature left field scoreboard with the Texas silhouette on it.
Fourth photo is from April 25, 1982 against the Brewers in front of a crowd of 36,866. Charlie Moore is about to step to the plate in the top of the 8th against Danny Darwin with the Brewers leading 7-6.
