The K B class were technically very similar to the K A class, but were distinguished by the inclusion of a booster on the rear axle of the trailing bogie and Nicholson thermic syphons in the Cass bank.

The B class locomotives featured an unusual design of firebox with two separate chambers, each with its own firedoor, divided by a water space that effectively acted as a thermic syphon, and joined at the tubeplate.

This can be either continuous removal or in batches, with the tap holes being blocked with clay at the end of a tap, and then reopened by drilling or with a thermic lance when it is time for the next tap.

It is made of a three-layered laminate : one gas-tight layer of Tedlar ( PVF ), one polyester fabric layer to provide stability and one polyurethane layer suitable for thermic welding that acts to connect the separate laminate panels.
48.
Boiler pressures rose as high as 310 lbs / sq . in .; thermic syphons added to the firebox and combustion chamber added 8 % to the efficiency of the boiler; roller bearings appeared on main axle boxes and sometimes on running gear.

Thermic refers to an average annual soil temperature between 15 and 22 degrees Celsius ( 59 to 72 degrees Fahrenheit ) and differs more than 5 degrees Celsius ( 9 �F ) between winter and summer at 50 cm ( 20 inches ) below the surface.

Winter's cold air pushes down the brown layer that normally hangs suspended over the city, and an increasing incidence of so-called thermic inversions have prompted Mexico City's Environment Commissioner to devise a plan to combat pollution over the long term.
