2.75 divided by 43 gives 6.4 %.
The calculator shows 0,06395348837209302325581395348837. You can multiply with 100 to get the percent value directly.

Yep, those rubber tires really let our stuff do some non-prototypical stuff, all in the name of 'fitting it in the small room in H0'. And I like that.

On Michael Portillo's program, I heard one of the loco drivers state that the incline they drive their locos on is 2% and that was quite steep for a railway.
Dereck

I heard somewhere, but have never verified the figures, that a 1% incline takes twice the power to pull a train at the same speed as it takes on the level.

One would need to go through the maths to work this out, and I haven't found the time to sit down and work it through, so ... anybody game?

Here in Sydney, Australia, our government railways have all the answers on prototypical rail inclines. They learnt this information the hard way. They planned a rail link between 2 stations (Chatswood and Epping) and on route there was to be a small bridge, but someone said that if they constructed the bridge it would endanger the lives of some frogs. So, they decided to build a tunnel - at some enormous expense, and they found that the trains couldn't go up the slope. No problem - buy new trains.

The same Government is now building a new metro using the tunnels which were built to our normal rail standards & clearances but there is also a long extension westwards joining on to the existing part which is built to totally different specifications which will not allow our current rail stock to fit thru. new signalling ,overhead , platform design etc etc . . At the other end the same tunnel boring machine is set up to drive under the Sydney harbor ,wander around underground till it comes above ground somewhere in the southern suburbs & then use the original rail line thru to Bankstown . with no possible connection or usage for existing trains . demolition of existing historical stations which are on the states register of historical buildings . All of this is to be totally driverless & controlled by someone in a remote building who has no knowledge of what is actually happening outside in the real world. A government that is hell bent on removing train crew from employment opportunities & have stated they will not be employing any more rail staff in future years . With all the current problems this mob have caused state wide with selling off the power stations , power lines , harbor control to overseas companies I cannot seeing them lasting much longerwhen the next election happens .


Cheers Tom in Oz .

Well since we are apparently playing "The Yorkshiremen" (I'll forgo the tale of how our metro area makes us lick the road clean and we got up 3 hrs before we went to bed)....

Seattle built a transit tunnel under downtown decades ago, that was prepared for light rail, and had rail installed in it, but only ran buses through it because Seattle was so farsighted in the 1970's or whenever it was, to think they would never grow and didn't need all that matching millions of federal funding (so Atlanta, Georgia got the money and built a great rail transit system out of it). And when Seattle finally got on the ball in the early 2000's (you know, many decades to late), they discovered those rails would not be usable for modern light rail trains they were looking at and had to rip them all out and replace them with new ones. Meanwhile, the very expensive bridge over Lake Washington that was built to some day take light rail, but over those decades was being used by Mercer Island residents to avoid sticking to the normal highway and High Occupancy routes, is now finally getting claimed for that purpose - and of course all the homeowners are screaming bloody murder and holding things up in court for reasons of "its all about me".

Buy is that Seattle in a nutshell. Pun intended.
During the period before they finally started building light rail there was this effort to extend the monorail system that was built ina small segment for the Worlds Fair back in 1962. They wanted to extend it over more if the city (at huge expense of course singe it's all gotta be up on concrete raises runs with unique cars). The voters of Seattle studied and voted and studied and cited. I think the monorail idea came up for public vote at least 4 or 5 times over the years as constant efforts were floated to add what would be a tiny fraction of coverage. When one thinks how much light rail cups have been built with the money spent on those studies campaigns and repeated elections it's maddening.

I recommended maximum 3 % incline and decline for the trains because most of the digital locomotives do have two traction tyres.
To pulling up wagons incline is already hard work for the locomotives with two traction tyres.
