In the Gloucester sim, I noticed that trains that are running with a loss of power simply plod up the Lickey Incline with no need for banker help. You'd think that some of those trains would need a bit of help up that grade... Semi-related sidenote: Is Distributed Power used at all in UK freight ops? (I know that US railroads use it extensively to avoid needing regular manned helper operations in mountain grade territory, among the other benefits it does bring...) Log in to reply |

The Gloucester sim doesn't include gradient code as far as I know. Saltley does, though, and you can see the effect on speed as a train comes up the bank. Distributed power isn't used in the UK. The idea of a "freight dmu" has been raised occasionally, but it's never gone beyond a loose concept. Log in to reply |

The other simulation with significant gradients enabled is Sheffield, from Dore up Chinley Bank to Earles sidings; IIRC most freight loses time.

I wasn't aware of any significant issues with Sheffield unless the bad weather scenario was selected (though maybe I didn't observe closely enough!). However, Carlisle has been noted for suffering significantly from gradient delays due to what was confirmed to be a core code issue. I believe that this has since been fixed in the core code that makes up the loader - Motherwell has a fair few steep bits as well, but trains run as they should.

I wonder if part of the problem here is the mix of MU systems in the UK? I suspect the Locotrol-type DP gear used in the US is designed to work with the AAR MU wiring... Log in to reply |

" said:" said:And equally, few industries have enough demand to require such long trains anyway - regular service is preferred over a once-fortnightly dump. Even if there was the demand, you could easily double the length of UK trains before getting into the territory of needing DPU." said:There is probably no need for distributed power in the UK as the infrastructure is not equipped to handle trains heavy and long enough to need such power (as discussed at some length in this topic).The Gloucester sim doesn't include gradient code as far as I know.
