Wheel flat?

Yesterday, I was on the UP express to the Airport and the whole time the train was making this awful sound. Particularly noticeable when we were departing Union and pulling into the airport.
Sounded like an animal in pain or something.
I would often hear this noise accompanied with the sound of the wheels screeching on the tracks.

I am not a huge fan of e-diagnosis, but will ask anyways - what were the symptoms? Sound was constant at all speeds vs varied by speed? Correlated to engine throttle (pretty easy to tell how hard the diesel is working and when it’s idling on UP equipment?) Came and went versus stayed constant at all times? Esp during station stops? Audible when you got off or only while you were on board?
We may never know, but if you would like a speculation it would help to know a little more detail.

The sound was more noticeable when the train was travelling at slower speeds, but it was constant throughout the entire trip. Even when we were going over 100km/h. It was especially prominent when we were pulling into Pearson.
The sound only stopped when the train stopped moving.
Like a low pitch, yelling sound.

If the sound was constant, you can eliminate most motor-related and HVAC/accessory-related problems as they would stop and start or change pitch as the throttle is used, or as compressors and such cycle..
Might be wheel, bearing, or braking related. Maybe a stuck brake or caliper. Obviously, I am speculating. If it was a one-of, and not safety critical, it would likely be caught nd addressed during overnight servicing.
In general, as a regular passenger, I don't find the UP fleet creaky, although the maintainers no doubt have their own opinion on things.

UP train is having some issues with trains. I think they had to take some of them out of rotation and service run every 30 instead of every 15 minutes now.

I'm sure that the weather isn't easy on the trains like the door mechanisms and such.

The architectural plans submitted for Woodbine GO Station submitted to the City of Toronto (https://www.toronto.ca/city-governm...nt/application-details/?id=4825832&pid=565431) on 2025-01-16 show 4 platforms configured for loco + 12 car GO Train consists, without separate (higher) UPX platforms.
Does anyone know if this means UPX won't stop at Woodbine GO or if the equipment being used for Union-Pearson services will have changed to be 610 mm loading height by the time the station is operational?

The Woodbine Station EA Report page 95 (dating from 2020) contains a statement that a UPX stop is not included but could be added at a later date. The EA drawings show the UP platform immediately west of the planned platform, on Tracks 2 and 3 only, above the underpass shown on this drawing.

Also something to keep in mind: the UP Express might be using different equipment by the time this station is finished, equipment that doesn’t necessitate a special high level platform.

That would require them to rebuild the other platforms to accomodate this station. How does that make sense

The general idea seemed to be that UPX would become more integrated with the GO system, with "Replacement of the existing diesel trainsets with electric trains that could also be used elsewhere in the GO Transit network once parts of that network are electrified", and "Elimination of high platform areas at GO stations along the route, with UP Express trains using the same platforms as regular GO trains."

Makes a lot of sense! Only one station needs rebuilding, which is Pearson. Unions UP terminal is already going to be abandoned, and the raised portion can just be removed from the other 3 stations as easily as they were installed.
Transitioning to low floor also allows UP to stop at additional stations once it’s electrified, without any additional infrastructure.
King-Liberty, St. Clair-Old Weston, and 1 additional station along the corridor are all potential stopping locations for UP post-electrification.
As said above the UP Express is becoming more or fully integrated with GO, which includes potentially interlining it with a service in the east, this can only be done with low floor trains.
