Hello everyone. Having acquired some WTTs for 1990, I am writing a timetable for the Gloucester sim. I'm really enjoying the process but have some general queries that I would like some help with. The first concerns entry and exit locations. Does a train enter the sim at line speed or start from 0mph? Is there any way to control this. For example, at Kemble, most passenger trains stop and so should have a standing start whereas freight trains should pass through the station at line speed. When a train exits the sim at a station, it seems to be common practice to record both an arrival and departure time. Does the departure time have any effect or is it for reference only? For example, if using a rule to prevent a train appearing too soon before it has had time to complete its "off sim" bit of the timetable, should the time of leaving the sim be the arrival or departure time at the boundary station? I have some more specific queries relating to operations in the Gloucester area but will post these in the Gloucester part of the forum. Log in to reply |

Trains enter the sim at "line speed". The departure time at the station is only included as each timetable locatoin must have a departure / pass time. So it's just for that really. Hope that helps.

So, a rule to allow for a train to run from Kemble to Swindon and back should be calculated from the arrival time at Kemble, rather than the departure time? And if the train has to wait at Kemble for the single line to clear, this time should be added to the rule?

You've confused me now! :S I understand the bit about a train terminating at a station on the sim. The departure time is meaningless to the sim but a useful reference point for the signaller. What is the effect at a boundary station? Is it just to block the section for longer? Log in to reply |

If it's a boundary station such as Bridgewate on Exeter, the sim will simulate the train being sat in the platform as specified in the arrival and departure times.

It really depends on how the sim is built as to what happens. Entrance It is possible for the developer to set a max entry speed (min 5mph I believe) but that will then apply to all trains. An option for the developer is to have a pair of entry points, one for stoppers, one for expresses with the speed set accordingly. I'm not aware of anyone having done that as yet. Another option is to have the Entry prior to the station and then timetable the stop as appropriate. Generally, however, I'd suggest you treat the entry as the departure time unless otherwise told. Exits The sim exit point is the end of a TC and if a train hits the end it falls off the Sim. The final Timetable location should be coded as the end of the TC if fall-off is required. Whether the train stops or not is irrelevant. However, if you set the stop position to a value short of the end of the TC it is probable that the train will never fall-off as it will stop and then there is no further location to reach. This can be useful for some sidings, for instance, where you may want some trains to fall-off but others to just pop in and back out. Peter I identify as half man half biscuit - crumbs!
