You should input files outside of the centreline command. You got the
error message because therion considered 'input foo.th' be the station
names without instrument readings.

You could also use

centreline
equate 0 at goon 40 at river
endcentreline
input goon.th

centreline
equate 25 at evening 18b at pt3.elevator
endcentreline
input elevator.th

which is not particularly nice  :(  We considered to allow the equate
command outside of centerline, which would simplify the syntax to

equate 0 at goon 40 at river
input goon.th

equate 25 at evening 18b at pt3.elevator
input elevator.th

It may be perhaps introduced in the future.
