Derby 23rd Febuary 2011
Agenda is:
Scheme design, exam technique, M1/7 discussion where appropriate
16:20 for a 16:30 start at DeltaRail, 2 St Christopher's Way, Derby.
All welcome from any background, company or with level of knowledge but. We are looking for regular attendees. Please let us know if you want to come in advance if possible.
See you there,
Jerry
PS: Networking afterwards in local establishment (even though the Harvester cannot reliably produce a single pint of Pedi!)
Group studied signal placement on M2 2009 mainline plan based upon the headway calcs previously derived. Several questions raised:
1) Does a signal that can display only a single red (exit to a main route) require an overlap?
2) How can a 3-asp signals be applied through station B when the braking distances don't support such?
3) Could a 3-asp head (green blanked) be used to exit from the spur with a R/G 2-asp starter?
4) What options are there when transitioning from 3-asp to 4-asp and vice versa?
5) Where do you start on the plan?
