There are currently 42 operational stations on Singapore's Light Rail Transit (LRT) system, a series of local automated guideway transit lines spanning 26.5 kilometres (16.5 mi) and acting as a feeder service to the country's Mass Rapid Transit (MRT) system. Conceptualised in 1991 and opened in 1999, there are currently three lines on the system: the Bukit Panjang LRT line (BPLRT), the Punggol LRT line (PGLRT), and the Sengkang LRT line (SKLRT). Of these, there are 13 stations on the BPLRT, 14 on the SKLRT, and 15 on the PGLRT. All stations are elevated and have barrier-free access and fixed platform screen doors. Four LRT stations interchange with MRT lines, being Choa Chu Kang, Bukit Panjang (pictured), Sengkang, and Punggol. These four are also the only LRT stations connected to bus interchanges. Three stations are planned to interchange with upcoming MRT lines: Choa Chu Kang, Punggol, and Riviera. (Full list...)

Fraunhofer lines

The Fraunhofer lines are a set of spectral absorption lines. They are dark absorption lines, seen in the optical spectrum of the Sun, and are formed when atoms in the solar atmosphere absorb light being emitted by the solar photosphere. The lines are named after the German physicist Joseph von Fraunhofer, who observed them in 1814. This image shows the solar spectral irradiance measured with a calibrated optical spectrometer, as viewed on a sunny day in Switzerland in 2022. Some of the characteristic Fraunhofer lines and their corresponding elements are indicated for the extended visible spectrum – the highlighted area of the graph.
