CREATE TABLE table_65122 ("Class  ( old )  to 1868" TEXT, "Railway number ( s ) " TEXT, "Quantity" FLOAT, "Year ( s )  of manufacture" TEXT, "Type" TEXT)

Can you tell me the Class (old) to 1868 that has the Quantity larger than 8?
SELECT "Class (old) to 1868" FROM table_65122 WHERE "Quantity" > '8'
SELECT "Class (old) to 1868" FROM "table_65122" WHERE "Quantity" > '8'
