According to Realtime Trains, the 11:18 from Newquay reached Par at 15:37, some 213 late.
The 09:04 Paddington - Newquay had to wait at Goonbarrow for the 11:18 departure, and reached Newquay at 15:50, some 93 late.
It is now on the return journey, the 14:55 departure from Newquay, but 60 late.
Given the late running of the 11:18 I am surprised the 09:04 was sent onto the branch and not held at Par.

802011 (1A86 11:18 Newquay to Paddington) failed shortly after departure from Newquay.
802114, which was working 1C72 08:04 Paddington to Penzance was terminated at Par and formed 1Z99 to run up the branch and rescue 802011. The combined units then formed 1A86, which was then terminated at Par 213 late.
