When I use the RunInterval code, when you approach the last
station, the train will be stuck there, which is annoying... Though
I have a few choices, like diverting the train to another track or
removing the code.
The problem why the front train is stuck there is due to the
permanent red signal over there. You should remove the red signal
and also the '0 km/h speed limit' then the front train will
continue. Anyway, it is understood that Choa Chu Kang is the
'terminal station'.
