I am not going to go back and quote some of the previous comments, although some will be addressed here. Consider this a start of several. I spent a little over 6 years on this system in its beginning, 1 1/2 years with a contractor and 4 1/2 years with DeLeuw Cather (the General Engineering Consultant) as a track engineer.
Track/wheel issues: Track gauge was originally set a 4'-8 1/4" on straight track and large radius curves and widened to 4'-8 1/2" on most curves with further widening as the curve radius got smaller. The 1/4 inch tight track gauge was chosen to presumably provide a better wheel/rail interface. Wheel gauge was set as normal for 4'-8 1/2" tracks. There were numerous issues involving tracks, wheels, truck stiffness, some of which were resolved early, and some which may never be resolved. I will skip this whole area for now.
The stations and underground sections leaking issues is a construction quality issue, and not one easy to fix. The need for good waterproofing was understood from the beginning, and to the best of my knowledge was properly designed and specified.
First, I truly love the open vault concept for the stations. The New York City subway stations and those of some other systems are claustrophobic. The relatively dim lighting was intentional. Weese wanted a "Cathedral" sense in the stations. Likewise, the vertical station name signs were part of this concept. "Like a candle in a Cathedral" were his words. The gradual darkening of the concrete with age and accumulated dirt appeared to not have been considered in the original design of the lighting. To paint the inside of the station vaults I regard as somewhere between being simply stupid and an abomination. A higher level of lighting is the only realistic solution. It does not need to be operating room bright, but it should be up to easy to read things bright.
More later.
