Hey Guys--
Been looking through my signal diagrams as I'm continuing work on the B Division route for Trainz 12, and I came across two interesting things--one has had me stumped for awhile, and the other is a recent find:
1) What does "UK" mean when printed next to some automatic signals? My hunch tells me it has something to do with keying by, but the "U" throws me off. Usually next to these signals there is an asterisk directing me to a note, and the note usually says "Installed a 10-sec key by timer for Signal _____". Any motormen willing to help solve this riddle?
2) I know that in the Second System IND plans, there were provisions to extend the 
past 205 St, but those were shelved along with the entire Second System when the Depression hit. The signal diagram depicting the 205 St station and its tailtracks was last updated in 1989 (according to the collection I have), and at the C1 & C2 bumpers east of the station there is a note that says "Temporary Bumpers". My question: Is an extension past 205 St still on the table at present? It would seem odd to have the note of temporary bumpers still present 60 years after the extension was shelved; if there are newer updated diagrams of this section (MW7C-1642), does that note still exist?
Thanks again!
