Just seen on ÖBB Instagram that there is a new NightJet Brussels - Vienna service. That's very handy for London-Brussels-Vienna! :thumbsup:

After initial disappointment that Eurostar to Brussels is indeed normally rather expensive, but I now see it's ony Ł17 from London to Brussels by Flixbus - perfect! :D

A morning of more backscene work.

So it turns out it is slightly a nightmare trying to retrofit stuff like this. I have finally managed to get the hill module back into a stable state (hurrah for the new hot glue gun!) after having to temporarily remove some of the supporting structure (first pic) for trimming it (i.e. violently hacking away at it). :D

Will need to prime the ply properly before painting, luckily know a bit about this stuff from my art painting background.

Will the backscene be removable so you can clean and maintain the track in the tunnel?   Often overlooked!

Yes Nick I had thought about that, but thanks for checking! It is to be removable not only for cleaning, but also for if I move. The idea for any future portability is to turn the layout into a kind of a wooden box, which would need to be the smallest volume I can get it.

If I remember correctly, most of the LED's I have used have been 3mm - not sure, apart from size of course, if there is any real difference.

I  suppose you might get a slightly better spread of diffused light with 5mm but probably not much difference.

There is a bewildering choice of LEDs to play with these days, difficult to know what's best for something like building lights. I've been impressed with the stick-on LED strips I'm using for my loco sheds.

Thanks chaps, oh yes lighting strips, there's yet another option!

Meanwhile, I've glued in some of my street lamps. Will need to have plenty more.

I wonder if these LED strips require resistors?

Or is resistance futile?  :D

They are the ones I've just been installing, from that seller  :D    They work just fine on 9V-12V with their built-in resistors but I found them too bright for the effect I'm after so I added a 1k resistor to each strip.  I used copper tape as the "bus bar" and unsoldered the supplied leads. 

As supplied each long strip draws about 160mA. With the extra resistors, all 6 strips under the large roof  are drawing 60mA in total.






I've used warm white strips in the workshop to be different from the cool white in the main shed

Totally brilliant Nick!

I think I'll buy them for my buildings and also get the same resistors to dull down a little. Is 1k about the same as the resistors supplied with the mast lamps?

Cheers
Matt

Yes that's right.   It's such a commonly used value with our 12V model railways it's worth having some in your bits box, and usually a good/safe starting point even if you find a higher value looks better.   In fact you've just reminded me I used my last one today, I must order another bunch  :D

Cool beans!

On the same note, my street lamps come with those same resistors. If I wanted to dull some of the street lamps further, what value of resistor would be a good starting point?

@Globibahn   Well if you don't want to buy a whole set of resistors with a range of values, for starters you could get some 1k  and try a second one in series with the street lamp to give you 2k total, or even try two more in series to make 3k total ... and so on until they look right.

The street lamps I'm using now have 4k7 resistors on 12V - so that's quite a bit more!  Where I have 3 of those lamps in close proximity I wired them in series with each other and with a 1k5 resistor.

Resistors cost pennies (I've just ordered 100x 1k for Ł1.69 as I want them quick, or you can get 100 for 99p from China). So if you find you prefer the look of say 2k, 3k, 4k or whatever total you end up with, then buy a bunch of the nearest available value to use instead of the originally supplied resistor.
