Bowenfels was 'Straight Railed' with all points removed along with the Upper Quadrant signals used between Bowenfels and Wallerawang East.
New single colour lights were installed but not in the same location or numbers as the Upper Quadrants they replaced.
The UP platform was removed to 'Improve Track Drainage' in the late 80's long after Bowenfels had ceased to be a working station.
Sometime during WW2, at least one train a day was run from Katoomba with employees of the Small Arms Factory to terminate at Bowenfels after the passengers alighted at the now removed Cooerwull platform.
The locomotive would 'Run around' at Bowenfels before taking the empty cars back to stow at Lithgow until required for the return run that afternoon.
This 'Cooerwull Special' did not appear as a service in the Public Timetable and no tickets were sold for the journey to the employees as it was run and paid for by the Commonwealth Government who owned and operated the SAF.
This train was eventually cancelled in the very early 60's as it was by then running most times near empty and the carriages used were the oldest unheated platform set they could find I think.
After the introduction of the single deck Interurbans, one train (211) ran out to Bowenfels from Sydney at around 2pm weekdays and stayed there about 30 minutes before returning to Sydney.
The Overhead is still very much alive and what you see in the overhead behind the Theatre Royal is the result of several changes over the years when an emergency crossover was installed and later removed as well as 'Isolating' switches for the overhead which were also subsequently removed.
The 'Grand Plan was for the Overhead to continue out to Wallerawang at least partly due to the proposed shunting Yard and Loco depot that was planned to replace Lithgow.
The East end of Walleawang yard was remodeled in preperation and along with some earthworks and track laid from Cox's River interlocking to where today a Coal loader sits on the site, it quietly awaits the arrival of the electrification.
