Question about the layout sheet and the notes.
Number 6 says that "Returning empties from the south are propelled from the Down Main onto the Down Loop and then run round."
However, the route boxes for 67 signal only gives three entries. Two we know must be for the main routes (the PLJI gives us that clue) and hence there is only one left for the shunt moves. Given that note 5 tells us that the "south" trains go have a run round and then propel onto the UM, this can only be done from the Up Loop so the shunt from 67 appear to be for the up loop. However, if note six is correct, we also need another shunt route from 67 to allow for the run round onto the train propelled into the down loop. Is this a typo. Should the train from the south be propelled into the up loop from behind 200 signal ready for the run round?
