A few fixes from last night:
The NYC Niagara's drivers locked up, last night, and I thought one driver went 'out of quarter' but, this morning, found that it was just a side rod screw that came loose: easy fix.
Derailment of one light wood kit but noticed that I was hoping to be able to use the old trucks but the wheel sets have no fillet next to the flange so these tend to derail under large loads (ie, lots of cars behind it).
One turnout in the Seattle's engine yard would only stay in the middle of the rails.
Had to re-solder the linkage. Surprising: would think a 40 year 'young' layout with only 100 turnouts wouldn't get these problems! 40 years in modeling is probably like dog years, ie 280 years! This being my 4th large layout, most of the wood has been used on each layout, dating back to around 1959. First layout at my parent's basement, 2nd and 3rd in Cleveland and my present, after a 'company' transfer, 4th layout started in 1979. My next move is '6 feet under'.
