North Yorkshire Moors Railway General Discussion

Has the propping of Bridge 42 started yet?

 

Website says £40 has it been reduced?

 

The new rates are from 1st March.

 

There's an interview with NYMR Trust Chairman Jeremy Swift on the Green Signals podcast starting at ~24:50.

 

Very interesting interview it is too.

 

Timetable now v1.1

 

And the 1410 Steam (supposedly) arrival into Whitby magically turns into a diesel for the return journey on the blue TT!

 

That is what note Y means. Diesel from Grosmont and all the way back to Pickering.

 

Another version appears, Pickering - Goathland only until 25/4

3 round trips, steam, same set

2nd train added from 11th April - assume this will be the AutoCar when it returns from Weardale.

Knew it ! You could see this coming a mile off. I'm staying just outside of Whitby for Easter with a family of six and we'd planned to do a Whitby to Pickering return, doubt we'll bother now. Speaking for myself and from a selfish photography point of view I could be easily pacified by them turning a few locos to face North as an apology. I wonder what the price difference will be now Grosmont and Whitby is off.

 

I assume you meant that in jest. Why would the (any) railway bother to turn locos for the benefit of photographers.?

 

And in reality it will have to be top and tailed due to the Goathland run around issues, so I'd suspect a diesel on one end for the majority of those trains. Hopefully the steam will be facing forwards on whichever end its on at least

 

According to Steam Railway 2253 is going mainline although the date of the first test is 1st April...........

Yes, in jest. Usually they turn one loco each year to even out tyre wear, so you never know.

 

And the date for this is........
I wonder how many more will fall for it?

 

People like locos to be going chimney first when working uphill. As a driver I'd prefer to be running uphill tender first, especially if a downhill followed.

 

I do as well, but I would not expect any railway to think about what we photographers may like on a non gala day.
Although I still remember an SVR Gala where I waited for No 9 which had gone into Kidderminster tender first and when it did appear it was tender first going back as well.

 

Care to elaborate on why?

 

Because of the way the water level changes over a summit. If you have a loco working chimney first, as you go up the hill, the water comes to the back of the loco so the water level reads high in the glass. As you go over the summit and shut the regulator (and possibly brake as well), the water goes forward. So you get a sudden drop in water level at the summit, to the extent that the water may in some circumstances completely disappear. That makes control of the water level harder; it is not unusual that you have to run with the water level out of sight over the top of the glass to ensure you have some showing in the bottom after the summit.

By contrast, running tender- (or bunker-) -first causes the water to drop in the glass as you go up the hill, and then rise over the summit. So you have more confidence in level; provided you can see the water somewhere in the glass going up, you know you will have water showing after you go over the summit and shut the regulator (and if the driver then brakes, the water level goes up even more, rather than dropping even more).

So essentially, when running chimney-first, everything works against you on water level as you go over a summit; when you run bunker-first, everything works for you.

How pronounced that effect is depends on how steep your gradients are, how tall the gauge glasses are, and the geometry of the boiler, and probably some other factors. But to give an extreme example, on the Bluebell we have a standing piece of advice on SE&CR locos (running chimney first) that if you can see the top of the water when approaching the tunnel, you probably already have too little to safely go over the top and down the other side. But that means that you always run those locos with the water out of sight on the high side, at which point your idea of your actual water level is largely based on intuition and experience, not on what you can see. By contrast on 80151 which faces the other way, you always have much more confidence about where the water is and you can run around all day with the water plainly in sight.

If you have a railway with the peak roughly in the middle and an equally challenging gradient either side you get used to the fact that it is “easy” in only one direction anyway.
