Identify a Peco Y point

Postby BrightHelmStone » Mon Dec 20, 2021 6:07 pm

Hi there
I have received three Peco Y points. I am trying to identify the model number.
They are old, as the frog links are not accessible.
I presume part of the Setrack range, but smaller than the current ST-247 point.

Anyone help me out with the model number?

It may be an early SL-97 Peco Streamline Wye point? Download this file, https://cdn.shopify.com/s/files/1/1541/1303/files/SL-97.pdf?v=1634032928 which is the current Streamline small radius Wye, print at 100% and see if its the same, length seems about correct.
It doesn't look like a Setrack point as there are no rail joiners fixed to the three rail ends. :D

Looks like a SL-97 to me. Not sure how useful they are except for very tight yard areas. The Setrack point looks better and can be freely mixed. It's effectively a medium radius point. If only they did an electrofrog version!

Definately SL97 from the 1970s/1980s at a guess - 610mm radius the same as the RH and LH SL91 and SL92. Current ones have tighter clearances to the check rails.

Yes definitely an early Streamline short Y. From the days before there were any electrofrog points. The very wide clearances in the crossing may give you problems with more modern slim wheels dropping into the crossing.

And unsuitable for DCC as it stands, as many OO wheels will bridge the rails at the crossing, especially as the flangeways are so sloppy as already mentioned.

Thank you for the answers.
No 'stuck on' fish plates so probably Streamline not Setrack.
The frog links are buried in plastic, so definitely old, as later Peco made the links accessible.
As in the photo, it is shorter than the modern SL97.
So I am going with an early version of the SL97.
Thanks all and Happy Holidays

The newer short Ys are not much better when it comes to shorting the two V rails together by a wheel with a wide flange. They are best treated as electrofrog even when if they aren't.

I'd be tempted to dig out the plastic point and solder in a little triangle of brass or nickel-silver to make it an actual electrofrog. I converted a long crossing this way and have plans to do a single slip when I feel brave enough.

A simpler way making a dead frog short circuit proof for DCC is to cut the fixed switch rails and wire together the rails from the frog so it is akin to a live frog.

Adding two IRJs to the Vee rail ends also prevents shorts and doesn't involve frog rewiring or switching or any other conversion of the Insulated frog point. Just add feeds of the correct polarity to the rails after the IRJs, as needed.
