These refurbishments started in 2019 with Green, Black and Silver. Then in 2020 Blue and Peach. now in 2021 so far we have Red and Orange. It is interesting to note that in 2021 they have started to replace the silver louvered vents on the exterior with black fiberglass replacements with smaller vents. Personally I think the black vents look better and blend in nicely to the tinted windows. Also they started adding Deltas to monorails that previously did not have any Deltas. Personally I think the Deltas going on nearly all of the monorails takes away from them a bit.
Blue got a Silver Delta
Red got a Black Delta
Orange got a Black Delta
Black got a Red Delta
Silver got a Black Delta
I rode Orange on Sat the 15th. Possibly the first day it was out on the beam? Anyway in my car the new orange bulkheads still had dust on it along the edges which looked to me like it was left over from the refurb process. You can see it on the first interior pic of monorail orange about half way up on the left side.
Also I did notice that on Saturday both Orange and Red had no automated spiel playing on the entire route circuit. You could hear the pilot though.
Lastly, here's my listing of these recent monorail refurbs by train and year. Some might find this helpful. Listed in random order by year.
