This procurement focuses on research and development services related to the enhancement of train safety systems, specifically addressing potential safety issues arising from the operation of new trains on the GB mainline. A supplier event will take place on Monday, 18th February, from 1pm to 3pm in London, with the engagement end date set for 28th February. Interested parties are required to submit their attendance by the close of business on 15th February. This tender presents significant opportunities for businesses engaged in research and development, particularly those with expertise in train safety systems and consultancy services. Small and medium-sized enterprises (SMEs) would find this opportunity particularly suitable, as they can provide innovative solutions and collaborate on developing potential adjustments to TPWS OSS settings that accommodate the performance of new rolling stock while ensuring railway safety standards are upheld. ## Notice RSSB is holding a Supplier Day on Monday 18th February in relation to "RSSB2776 - TPWS Overspeed Sensor System (OSS) Setting Optimisation (T1174)" from 1pm - 3pm. Should your organisation wish to attend please email the following email address by COP Friday 15th February: Shareditt@rssb.co.uk -- Following the introduction of new trains with improved braking and acceleration performance operating on the GB mainline, there has been an apparent increased rate of Train Protection and Warning System (TPWS) Overspeed Sensor System (OSS) trips. There is a belief that this is because drivers are now driving to the increased performance of the new rolling stock and starting to brake later, at a point that would still allow them to comply with company professional driving policies and to stop at the signal or comply with the reduction in speed. However, this has the result that the train passes the OSS at a higher speed than the OSS is set for and the trainborne TPWS reacts and applies the emergency brake on the train. This research will establish whether and what alternative trainborne TPWS OSS trigger delay timer settings could be applied to trains with better performance, without compromising the overall effectiveness and availability of the whole system or the safety of the railway. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/7c2e519f-9edb-45bd-a523-fbd8fa987a74 | | Notice type | Market Engagement Notice | | Procurement type | Standard | | Procurement category | Not specified | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 19 Feb 2019 | | Submission deadline | Not specified | | Future notice date | 28 Feb 2019 | | Award date | Not specified | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planning | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | RAIL SAFETY AND STANDARDS BOARD LIMITED | | Locality | LONDON | | Post town | Central London | | Postcode | EC2M 2RB | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI4 Inner London - East | | ITL 3 | TLI43 Haringey and Islington | | Local authority | Islington | | Electoral ward | Bunhill | | Westminster constituency | Islington South and Finsbury | | Delivery location | Not specified | ## CPV Codes ### Divisions - 73 - Research and development services and related consultancy services ### Codes - 73000000 - Research and development services and related consultancy services ## Release History - 19 Feb 2019 at 10:18 - Planning - Market Engagement Notice - https://www.contractsfinder.service.gov.uk/Notice/7c2e519f-9edb-45bd-a523-fbd8fa987a74 - 11 Feb 2019 at 14:47 - Planning - Market Engagement Notice - https://www.contractsfinder.service.gov.uk/Notice/7c2e519f-9edb-45bd-a523-fbd8fa987a74 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/7c2e519f-9edb-45bd-a523-fbd8fa987a74 19th February 2019 - Early engagement notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/c99c7271-f9f4-40ab-8cbc-947ef148164e ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
