<{POST_SNAPBACK}>I thought someone was jesting when they started talking about Cl 13s !!! i had never heard of them let alone seen one, its an interesting concept but did it work, and why build it in the first place, was there not a heavier locomotive that could have done the same job? from a practical point of view, why where they built in the first place was this configuration more cost effective or was there no other locomotive to tackle the job?
Prior to their introduction Tinsley yard used a pair of 08 shunters semi permanantly coupled together, however as fas as I am aware they were not fitted for multiple operation, which meant two crews. The reason for the doubling up was, I understand, that with the gradient at Tinsley yard a single class 08 did not have suffecient weight or power to propel the trains to the hump within the yard. From the practical point of view there were no larger locomotive suitable to do the job as main line type 1's were too high geared to be succesful shunting locomotves. They continued to do the task in hand until Tinsley hump yard closed.
Hope this bit of background helps.
