Notes / Anmerkungen

Due to the habits of railway terminology, "load" here means the mass of any wagons and carriages including their payload (passengers, freight) but does not include the mass of any engines. In the case the formation consists engines only (including multiple units), load is defined to be zero and does not include the mass of any passengers or freight (which may be conveyed or transported inside the engines or multiple units).

However, the attribute weight contains the total physical mass, always including all engines, multiple units and payload.
