Hi just a brief introduction of myself. I live and work in Australia and am building a Dutch layout. In the old Utrecht central station they had around 6 sets of these. It allowed short EMU's to stop at say platforms 4a and 4b. Yet a long train would be just at platform 4 taking up both a and b sections. Short trains could pass each other through the centre.

I want to build this in HO 16.5 mm with a track distance of 51-54 mm and in code 83 FB.

I am familair with CAD and find this program very impressive. I have built over the years a number off ordinary points but not an assembly like this.

I would prefer symmetrical 3-way points (frogs at the same alignment), but non-symmetrical ones will be fine too.

Is there someone out there who has built something like this and could share the template please?

Regards

Cornelis

Hi Cornelis,

Welcome to Templot Club. :)

That's a common operating practice at UK stations too. I think you mean a "scissors" crossover?

If you post a track plan or photo, we can be sure we are talking about the same thing.

regards,

Martin.

Hi Martin
Yes that is more or less it. However I like to have a triple sciccor crossover. I had already uploaded a picture (see gallery) but will do it again and try inserting this time.

Never thought about it before but how do P*c* get the frogs on a 3-way aligned? Is the left-hand road sharper than the right-hand road?

Hi Nigel.
It depends on the formation.
With a Tandem Turnout, the two base turnouts will need to be somewhat different in order for the two far crossings to have their nose on the same A timber and allow the first set of switches enough distance to clear the second set of switches. There will be a limited number of combinations where this is possible.
For a Three Throw Turnout, where the switch blades coincide, both base Turnouts will be the same just of opposite hand.
Regards.
Tony.

Gents

I came across this guy from Indonesia who builds these and also other point configurations as custome made to order.

His work is very good. I had some other things on my mind so I had them built. His turn-around time was 3-weeks. I told him I was not in a rush. The arived just under 5-weeks after order/payment.

He charged $435 USD for the two sets in code 83 Micro Engineering stock rails inc delivery. His name is Andreas Jodie but insists on being called Jodie. I tried explaining to him that is rude in our view but that didn't make any difference. I gave him a $40 USD tip of which he only accepted $20 USD.

Here are some pictures. Electrically only the frogs are isolated, I have not ran a train over them but with the multimeter it sure works well. He used double sided PC board, that would be how he got the polarity transferred to the crossings and wherever PCB's are not required; he used laser cut timber for the ties. The running characteristics of stock coaches is superb.

The rest of the simple points I will be making myself and will use templot for the templates. I know sharing these images is kind of risky on this site! However this is worth knowing.

His email address is: pinguintrains@gmail.com

Regards

Cornelis
