| Summary: | The Gemas – Johor Bahru Electrified Double Track Project (GJBEDTP) is the most recent railway electrification. GJBEDTP runs from Gemas Railway Station to Johore Bahru (JB)
Sentral. Since the JB Sentral station platform track is existing, it cannot achieve the minimal offset in the client's Statement of Needs (SON). The station canopy's acting load capacity is limited, so it cannot support the Overhead Line Equipment (OLE). Malaysia's standard offset value was 3.0 m, while the KTMB guideline's maximum offset value is 3.60 m and the minimum is 2.60 m. Thus, this research investigates the
concrete mast offset that should be used when track separation is lower than standard. JB Sentral architecture data was collected to evaluate the mast offset. Sicat Master
simulation and a cross-sectional diagram can be used to determine the proper minimum offset from the data collected. The results show that the mast at the centre
of the two tracks can achieve clearances with the minimum offset of 1.80 m from the track centreline to the concrete mast face. These results also show that tangent track
alignment allows a minimum offset of 1.80 m at a lower train speed. |
