Question bout SMEE's?

Wouldn't all single end single cabbed cars be considered SMEE's wether they were semi-permentally coupled or had draw bars, that ranged from r26-42's? Because the married pairs shared components. I.E. one car had the battery and electrical mumbo jumbo and the other had the rest of the components, basically split in half,right? just wanted to know,thanks:)

SMEE stands for "Straight-air Motor Car Electro-pneumatic Emergency". Everything from R10 to R42 and the R68s (the TA did a tech backtrack after the "fun" they had with 44s and 46s) use "SMEE" type brakes

 

don't overlook the R62's either. =)

The "electrical mumbo jumbo" vs. other components was simple. One car contained the battery and inverter/motor generator (charges the battery), the other car contained the air compressor which provided air for use in the braking system (and, on R10's, the doors).

 

SMEE comes from a description of the braking schedule on the cars:

Straight-Air (increase in trainline air pressure applies the service brakes)

Motorcar (braking system for use on motorized railcars)

Electropneumatic (service braking system is electric - dynamic brake - and pneumatic - friction brake)

Emergency (emergency braking system equipped)

Well, for (Remaining) SMEE cars, there is good news, just spoke to a TSS @ dekalb and he said the 32 and 42s will both retire after 2017

 

and you believed him? lololol he was trolling you! The R42's will be gone BEFORE 2017.
