The way we like it! Just wish most stuff was under the 150 quid mark!

 

That looks fab Lad. 

Are the Coaches Squeeking?

No my Silver Fox van at the back is squeeking.

I received my Park Royals this morning. They look amazing, but I think I can see what's been causing derailments for others.

One of the brake lines on one end droops down and fouls the flange of one of the wheels:

This is a lot easier to see on the green coaches with the grey brake lines. The video shows the worst affected of my PRs, but all of them seem to have some level of contact with the wheel. This only happens at the end where the two lines cross over, the other end has enough clearance.

I have not actually experienced any derailments, but I could see this causing problems especially in combination with some iffy track.

I will be regauging mine so the wheels will be moved out, well away of these lines. But otherwise I reckon a drop of glue to stick the brake line to the underside of the floor might be the best solution.

My little take on the Park Royals.  Really well executed model.

As a noob, I have to ask why regauge, and how? 

Any videos that describe the process? 

Just curious  

Thanks

The 16.5mm gauge OO track most people use is slightly under scale for standard gauge. It's actually really HO scale track that we use in OO. Some modellers in the UK use EM and/or P4 track and wheels which are more accurate to scale.

In Ireland the 'problem' is doubly bad since we use broad gauge track, so the scale accurate track gauge should be 21mm instead of 16.5mm. So some modellers (like me) who care too much about accuracy or just like the extra challenge will regauge stock to run on 21mm gauge track.

 

I'm sure you can find a few videos around the place on EM/P4 conversions (especially from UK modellers). It usually involves pulling the wheels out to the correct gauge, but depending on the model can require some more significant modifications. There are quite a few posts on this forum about people converting their stock too.

That's putting it mildly.

Seven scale inches too narrow for standard gauge. A whole 1ft 1½ins too narrow for Irish standard. And that's all due to decisions made, and the state of electric motor technology, in the 1930s...
