Scenarios – Freight demand• Forecasts from MDST study for Network Rail (Freight Market Study)
– Current, 2023/4, 2033/4, 2043/4 (Focus on 2033/4)– Increased fuel & wages: Bad for road = good for rail– Additional rail-connected warehousing nationally– 20% increase in operational days per week and intermodal train length
with equivalent improvements for road– No Avonmouth deep sea container port
• Locally, assumptions include:– South Staffs rail-connected warehousing– Cannock intermodal terminal– Rugeley partially converts to biomass– No Bescot intermodal rail freight interchange
• Key results– Significant freight growth in / through West Midlands– Particularly high growth in intermodal– Coal declines and partly replaced by biomass

Unconstrained growth:demand for paths vs capacity
• Forecast demand for train paths during daytime off peak 6 hours given unconstrained freight paths plus (aspired) passenger services
• Train path volumes shown are sum in all directions through junctions• Theoretical Max capacity assumes existing Timetable Planning Rules • “Junction simple-CUI” (JSCUI) calculations imply ‘stand-alone’ junctions

Congestion hotspots - commentary• Those currently considered very busy (JSCUI%) max. out at
60% utilization (impact of one junction on the next):– Water Orton (60%) Aston (47%) Galton J (51%) & Soho SJ (56%)– Water Orton highest JSCUI with 60%
• Currently spare capacity through– Ryecroft J (21%) & Bordesley J (21%)
• Little growth forecast at most currently-busy junctions– Aston (49%) Galton J (43%) & Soho SJ (55%)
But large increase at:• Bordesley J (42%)
– Becomes busy – compromises may allow it to be time-tabled• Ryecroft J (56%) & Kingsbury J (57%)
– Become very busy – challenging to accommodate• Water Orton (87%) - Cannot be accommodated
Findings: Water Orton corridor• Water Orton is key bottleneck in West Midlands• Strong unconstrained demand would outstrip
corridor capacity– needs to be resolved to accommodate future growth
• Needed to determine (conditional) output requirements of corridor to investigate solutions
• Water Orton capacity constraint needs to be resolved for Tamworth / Nuneaton local rail service (via Camp Hill) to be launched
Study Findings- Camp Hill South• Study has identified potential incremental scheme which
does not require S-W-L scheme• Kings Norton – Moor St. 3 services/hour + freight feasible
– Assumes Kings Norton additional turnback platform off the main line to avoid conflicts with route to New St.
• Camp Hill chord south could be built first– Could be developed with passive provision for north chord
• Need to establish business case and viability of options• But removal of freight services or signalling upgrade may
be required to reliably deliver > 3 services per hour

Water Orton – partial solutions• Divert freight to Stourbridge-Walsall-Lichfield
– Easily-switchable trains reduces demand slightly: 157 to 145– But costs probably not justifiable
• Whitacre East chord– or chord at Lichfield from WCML towards Rycroft/Sutton Park?
• Restrictions on freight thru. W. Midlands?– Other freight re-routings involving longer distances & costs– Unpopular with freight operators– Could add to other capacity issues elsewhere (WCML full!)
• Improved signalling• Compromise on fast passenger timingsBut probably need new tracks for full solution such as:• Grade separation at Water Orton and/or Whitacre Junctions• Dedicated freight route west of Whitacre Junction
Proposal to Network Rail• A solution to Water Orton is required
– Start GRIP process– Establish relationship with Strategic Freight Network. Can SFN
contribute to enhancement?
