Cutting hole in the top of train station

Drill a hole then use a Dremel tool with a bit like the one on the right.

Drill a series of small holes in a row and file it into a slot.

Bit saw. You can control it easy.

or step drill cutting.

Andre.

Careful use of a Dremel with a cutting blade will also work.

The slot I need is a little less than 1/64 x 3/4.  It is just the card part of the sign.

What is a bit saw.

Thank You

You can do an elongated hole with a 1/16" (.0625) drill bit. Then use this small, (Sawzall), reciprocating saw blade.  The blade is. .052" wide.  There is a handle available for the blades so that you can use care when cutting.  Picture is with the handle.  Note that the set-up cuts on pull instead of push.

Edit/Add. 

The  powered version is much more intense. 

Longer blades can be flexed.

Closest that I could fine to a similar product. Click on the underline phrase to link.

This hacksaw blade holder also has a lot of worth, IMO.  I've ground one end of a hacksaw blade to a point.  The blade can be used in either cut direction.

Interesting!  Looks like two tools I need to get, to save hand drilling and cutting.

I depends on the width of the slot.  I would definately drill holes at both ends to start the slot - using a drill press to keep the bit aligned, etc., if you have one, or very carefully if you do not.  The Dremel would be my choice but the narrowest high-speed cutter bit I have seen is about 1/8 inch.  Since the slot needs to be thinner than that, I'd drill lots of holes as your were advised above and cut out between them with a thin blade such as a sabre saw's.  It would be more than 1/64 but when I mount a sign, etc., like that, I generally make the slot a bit wider than I need and fill it with the glue/cement.

Can you take the roof off the drill from the inside in the valley of the interior?

That width is only a bit under 0.016 and using a drill of that size repeatedly to create a slot, or even the beginnings of a slot might be tricky to keep in alignment. 

Might need to go a bit larger and then fill back in with some styrene and glue. If you can get an opening started I'd just make it a bit larger and get the length set using a regular razor saw.

If you have a steady hand, you could also try using a Dremel with a saw blade (~0.007) being exceeding cautious to retain all body parts in their starting state of connectivity.

What mwb said.

Got the hole in 1/16 bit & utility knife.  I thought it might be a resin material but it was only plastic.  Thanks for all your inputs.

USE A DIAMOND OR CARBIDE SMALL HOLE SAW.  IT WILL NEVER CRACK OR CHIP ANY MATERIAL. IF YOU LIVE IN THE CLEVELAND / MEDINA AREA, I WOULD GLADLY DO THIS FOR YOU.

Here is a picture of the finished job

Good for you; looks great!

Love Miller stuff. 

That at looks great.

PS: What power supply are you using?

I've done several with Dremel and 1" cutoff wheel. No need for predrill.

The Miller Engineering that will power 6 signs 4804

Hi Ken, Very nice job on your sign!I did the same with a larger MTH station, and used a cut off wheel on the roof for a Miller PRR Railroad sign! Mr. Miller has done some great signs and I have 6 on my layout! They really add a lot of pizzazz and bring a lot of nice comments! 

Thank you all for your very nice comments & likes
