The line was opened in 1866 to carry slate from the quarries at Bryn Eglwys to Tywyn
Correction

The Talyllyn Railway opened in 1865 for slate traffic. 1866 is the year its passenger service was formally approved and began.

Full reasoning

This sentence appears to conflate the railway's freight opening with its later passenger opening.

According to the Talyllyn Railway's own official site, the line opened in 1865. Its history pages then explain that 1866 was when Captain Henry Tyler inspected the line for passenger service, after which it was approved to open to passengers and a December 1866 timetable was issued.

So the part claiming the line was "opened in 1866 to carry slate" is incorrect. The railway was already open for slate/goods traffic in 1865; 1866 refers to the start of passenger operations, not the opening of the line for carrying slate.
