Newbies, Dont try this

i might be wrong--its still early in the day--but isnt a c-train hooked with a pintle hook?
i am only used to seeingb-superb and super super b---but mainly super b's

 

An "A" train is, and those have the removable dolly. A Michigan gravel train might be a "C" train. The dolly is permanent, and the pin can be locked when you "try" to back it up, but the pup is still conected by a pintle setup.
Glad I'm not the only one

 

i used to know--it might come back yet
god i hate alzhiemers---almost as much as i hate trains
now everybody in canada is using and pushing for the lcv's
but it seems at least they just dont let anybody pull them and are pretty strict on them--i believe so far they have proven to be very safe

 

LCV, the full doubles that come out of PQ?

 

yes-they have been running them out west for quite a few years
but just recently in the east

 

Here's the low down from my neck of the woods. A train-single pintle hook dolly 2 or more trailers w/ 7 or more axles. C train-double pintle hook.(More stability)

 

Oh boy, what's a double pintle hook?

 

Wasn't Ontario trying to stay away from them?

 

DOUBLES: A-Train, B-Train, C-Train; Tractor towing two Trailers
The common 'double' configuration is called an 'A-Train'. It is similar to a regular tractor semitrailer combination with a following full trailer. The full trailer is usually composed of a single or double axle dolly ('A' dolly) that has a drawbar that connects to the rear of the first semi-trailer and has a 'fith wheel' mount for a second semi-trailer. The drawbar of the dolly is usually fitted with a pintle 'eye' that connects to the pintle 'hook' which is mounted at the rear of the first semi-trailer. A second semi-trailer is hitched to the dolly 'fifth wheel'. Brake and electrical lines join the trailers.
The pintle eye is usually horizontal on the dolly drawbar. The eye should be allowed to rotate on a longitudinal axis at the front of the drawbar to avoid failure if the second trailer rolls over. The drawbar tows a single non steering single axle two wheel dual tired dolly. Two axle dollies are used when the allowable load for a single axle would be exceeded. The drawbar has freedom to pivot on a transverse horizontal axis at the dolly. The dolly has a standard fifth wheel to hitch the second trailer.
A 'Western Double' (US) is an A-Train with two equal length (up to 28 ft) trailers with an overall length of 65 to 68 ft (20 to 21m). In Canada the maximum length is 25m. 'Turnpike DOUBLE' is a US term for a unit composed of a tractor and 2x45ft long trailers. The are used in the western US and on some Eastern Toll roads (eg. NY Thruway, & Florida Turnpike). Another combination is called a 'Rocky Mountain DOUBLE', i.e. a tractor with a 45 and a 27/28 ft trailers. These as the name suggests are used in the western US states.
A 'B-Train' has a special lead trailer with a rear mounted fifth wheel. The 'B-Train' is favored by the Canadian regulations because of its increased dynamic stability and higher payload for the same overall length. The second trailer is coupled on the fifth wheel at the rear of the first trailer. B-Trains have more yaw stability and roll coupling than the others. B-Trains are allowed higher loads in Canada. 'B-Trains are usually special purpose machines that remain together as a pair.
The 'C-Train' is similar to an A-Train except that two drawbars are used to eliminate the freedom to rotate about a vertical axis at the hitch point. The dolly is equipped with a self centering, self steering axle that requires a side force of about 0.3g to steer. Canadian regulations allow slightly higher loads on C-Trains than A-Trains.

TORONTO, Ont. -- The provincial government has quietly removed the 'pilot' tag from Ontario's long combination vehicle (LCV) program while doubling the number of carriers that can participate.
"The ministry is moving forward with a limited expansion of the Long Combination Vehicles (LCV) Program starting in March 2011," Emna Dhahak, senior bilingual media liaison officer with the Ministry of Transportation confirmed to Trucknews.com. She said that to date, 80 permits have been issued to 40 carriers. This year, an additional 40 fleets will receive two permits each, Dhahak added, effectively doubling the number of carriers involved in the program as well as the number of LCVs approved for travel in Ontario.
However, each carrier will still be limited to just two permits this year, which has caused some grumbling among the fleets who helped pioneer the program. Some of the first fleets to climb aboard Ontario's LCV program have invested millions in equipment, training and facility upgrades
