No, because TE is a calculation from the co-efficient and the vehicle weight.
Weight of the vehicle can change during gameplay (for example, an engine with cargo capacity, or a bus), this changes the calculated TE value.
If you're working on setting real-life TE values I wouldn't worry about being super accurate:
- TE figures are often 'nominal', i.e. calculated based on weight on the drivers, rather than measured on a train
- actual measured TE varied between different engines of the same class
- actual TE varies as the engine uses up fuel, water etc
- actual TE varies with rail conditions
- lots of the figures come from Wikipedia, and train fans in forums call it Liarpedia but eh
