dates for Amtrak's phase paint schemes?

OK Amtrak modelers, after searching for an on-line resource for 15 minutes I have come up empty on finding the actual dates that the various phase paint schemes were introduced.

From my memory and/or the Microscale catalog I have this:

phase 1: 1971 - 1975 or '76

phase 2: 1975 or '76 - 1980?

phase 3: 1980? - 1994

phase 4: 1994 - 2001

phase 5: 2001 -

A customer and I need to find as exact a date as you can give us on when the different phases were introduced.

He is modeling 1978 and I’m sure he can use the phase 2 scheme, and 1.

I am modeling December of 2001 and wondered when the phase 5 was introduced in 2001 (if indeed that year is correct) and if any phase 3 painted cars, such as MHCs, might still have been around.

Or can someone point me in the direction of a resource that would have these answers?

Any help will be greatly appreciated!

edit: went to the fallen flags site and found a few shots of ph. 3 cars in the 2001- 2003 years, also will check my own Amtrak photos sometime this weekend. Also found some shots of the ph. 5 scheme in early 2001on the fallen flags site. Should’ve gone there in the first place.

Any other advice on Amtrak paint scheme dates would still be appreciated.

Someone please confirm or correct these dates! I’m looking for them as well.

Also… by when did the old RR liveries fade out please? TIA[8D]

Wikipedia gave a bit: http://en.wikipedia.org/wiki/Amtrak_paint_schemes Apparently Phase 3 was introduced in 1979, and the Phase V scheme was introduced along witht the Acela Express, placing it around 1999-2000.
