Spotted one error in my X28 article which is entirely my fault on page 31:
Current: Class X28A can be distinguished from Class X29 by its taller height and six panels to the left of the door, including a narrow panel second to the left of the door.
Corrected: Class X28A can be distinguished from Class X29 by its taller height and a narrower panel second to the left of the door.
A correction will be published in the July TKM. Apologies for any confusion.
