The classical kind, of course
If two trains leave a station o nteh same track. An observer missed both these trains and is standing clsoe to the track sees the westboun train recede at 0.6c and sees the eastbound train recede at 0.8c. There is a ticket collector on the westbound train going from the back of the train to the front at 0.4c, with respect to a passenger on the westbound train.
If the GALILEAN transformation equations were true then what would the speed of the eastbound train with respect to the westbound train (call it Ur) according to:
A) Observer on the station - i would say 1.4c because that what he sees, right?
b) Passenger seated on the westbound train - 1.4c becasue if he looked behind out hte window he would see the eastbound train go 0.8c + 0.6c away from him
c) Ticket collector on the westbound train (still walking from back to the front) - 1.8c (her speed 0.4c + speed of train 0.6c + speed of east train 0.8c)
Similarly what is the speed of the ticket collector:
d) according to the observer on the station - 1c - speed of the train + TC speed
e) according to passenger seated o tneh east train - 1.8 c
f) relative to a passenger seated on the east train according to to the observer on the station - 1.8c
remember this is using classical relativity, not special relativity, please tell me if i made any mistakes
