Then again, the "smooth ride" selling point might have been moot if any noticeable banking took place. I'm always just a bit shocked and saddened at the quantity of really low speeds on the route, feel like I never see anything outside of 10-30kph.
You can also thank the simplified fixed-bogie configuration for those low speeds - as well as the complexity of designing the entire line transition spirals in and out of every single curve.
Nose hunt at higher speeds is something to watch for, especially on the shared freight Southbound alignment on the Waterloo Spur, where that track will take more of a beating than the Northbound one.
Acceleration rate is also something that drove some of the very low speeds in some areas, coupled with the curve geometries.
