Safety control system configured for interlocking a Mechanical Gap Filler (421, 422), hereafter MGF, with both a Platform Screen Door (111, 112), hereafter PSD, and a Guided Vehicle Door (211, 212), hereafter GVD, of a guided vehicle at standstill along a platform, the safety control system comprising: - a communication device for communicating with a GVD control system, a PSD control system, and a MGF control system; - a processing unit capable of exchanging data with the GVD control system, with the PSD control system and with the MGF control system via said communication device, the processing unit being further capable of determining from said data an extension/retraction state of the MGF (421, 422), an opening/closing state of the PSD (111, 112), an opening/closing state of the GVD (211, 212), wherein the processing unit is capable of generating at least one of the following signals: i. a first signal configured for either triggering an opening of the PSD (111, 112) and GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "fully extended", or preventing the PSD control system and the GVD control system to open respectively the PSD (111, 112) and the GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "retracted" or "partly extended"; ii. a second signal configured for either preventing the MGF control system to retract the MGF (421, 422) if the closing/opening state of the PSD (111, 112) or GVD (211, 212) is "fully opened" or "partly opened", or triggering a retraction of the MGF if the closing/opening state of both the PSD and GVD is "closed". - a communication device for communicating with a GVD control system, a PSD control system, and a MGF control system; - a processing unit capable of exchanging data with the GVD control system, with the PSD control system and with the MGF control system via said communication device, the processing unit being further capable of determining from said data an extension/retraction state of the MGF (421, 422), an opening/closing state of the PSD (111, 112), an opening/closing state of the GVD (211, 212), wherein the processing unit is capable of generating at least one of the following signals: i. a first signal configured for either triggering an opening of the PSD (111, 112) and GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "fully extended", or preventing the PSD control system and the GVD control system to open respectively the PSD (111, 112) and the GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "retracted" or "partly extended"; ii. a second signal configured for either preventing the MGF control system to retract the MGF (421, 422) if the closing/opening state of the PSD (111, 112) or GVD (211, 212) is "fully opened" or "partly opened", or triggering a retraction of the MGF if the closing/opening state of both the PSD and GVD is "closed". i. a first signal configured for either triggering an opening of the PSD (111, 112) and GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "fully extended", or preventing the PSD control system and the GVD control system to open respectively the PSD (111, 112) and the GVD (211, 212) if the extension/retraction state of the MGF (421, 422) is "retracted" or "partly extended"; ii. a second signal configured for either preventing the MGF control system to retract the MGF (421, 422) if the closing/opening state of the PSD (111, 112) or GVD (211, 212) is "fully opened" or "partly opened", or triggering a retraction of the MGF if the closing/opening state of both the PSD and GVD is "closed".
