Passenger line speeds.

Post by Mike_R » Wed Nov 14, 2012 8:11 pm

A question was asked at the Broadclyst meeting that I didn't know the answer to.

Would yard limits be enforced on the approach into a station? or would it be treated as line speed, especially when departing?

So on my module, 11th Avenue, the freight yard would be 15 mph, but the platform approaches and mainline maybe higher.

I am not certain , but I've seen footage on Youtube of us passenger trains passing through a station at considerable speed, although perhaps this being a center track between the actual platform tracks (so a minimum of 3 tracks between the two platforms, with the higher speeds away from the platforms). In Holland, it's not uncommon on smaller stations to see a train pass the platform at higher speeds, and the same is true for the UK. As many rules are based on the original UK railway signaling system etc, I wouldn't be surprised to see the same or similar rules in the US.

Perhaps someone knows more about this.

Hi

There are two questions here which is important. and I may be a bit 70s 80s. So there are two rules.

Yard Speeds did not apply to scheduled first class trains. They went through fast.

I seem to recall that speeds through stations depended on if there was another passenger train in the station. Indeed I think one had to stop if the moving train was passing between the depot and the parked passenger train.

But the two are (were) different.

All the best

The other one, as 11th was set up as a terminus the other week, and two of the three passenger platforms were accessed via crossovers you would have a speed restriction into those tracks, if not all tracks.

Approaching the terminal, trains would be slowing to enter the platforms, but on leaving would only be restricted by the turnouts, maybe medium speed.
The real question is are the passenger tracks inside yard limits? I think that they are not, as the passenger tracks are separate from the freight yard.

In terms of your track layout I would agree - although it would mean passenger shunt moves would presumably need dispatchers (or signalled) permission?

For a passenger terminal remember that "Yard Limits" ONLY apply to the main track so as soon as you pass the first turnout away from the main track you are on secondary track with its own rules and speed limits.

Also "Yard Limits" does not apply within an interlocking which again would be commonly the way to handle a busy passenger station.

As a through station again "Yard Limits" only applies to the main track and only restricts the speed of trains other than first class which may pass through at line speed.

The main constraint will as mentioned before be the turnouts where our No 6 turnouts probably represent a speed of 15MPH which even applying selective compression will hold all train movements to almost walking pace.
