Coffin boxes on cabs

[stretch]

If Engines 44, 160, 250 and 274 are the Haz-Tech engines then what are engines  72 and 165? They both have the long coffin boxes on their cabs. While Engine 168 has a shorter box on the cab.

165 is HazTec.
I'm not 100% sure but I believe 72 is water rescue gear.

Most boxes are just used for equipment that is hardly used......... Also the sizes are decreasing as newer
