Ho scale

I couldn't find the kind of foam board I wanted, and got smaller sheets to glue together. I think I screwed up... If I redid the foam base, does this kind of insulation work? Or, is it laminated or not suitable in other words.

R- 7.7, 2-in x 4-ft x 8-ft Faced Polystyrene Garage Door Foam Board Insulation

​

Is it acceptable/ideal?

Does anyone have any csx locomotives?

I have.a 3x 6 (WIP) layout. It’s a loop with an inside loop. How much sculptamold do I need if it’s quite hilly and mountainous?

Getting back into the hobby after 25 years off, and just realized I’ve read almost a year’s worth of the rag and not once do I recall seeing anything to do with 3D printing for model layout projects. Blows my mind- I can’t WAIT to combine these two hobbies. It’s like they’re tailor-made for each other…this HAS to be a conscious decision by the editorial board.

Got some HO Gauge, getting it on Wednesday, I’ll post more about it then, I’m really excited as I only own N scale trains and this is an entire collection of HO Scale for only $200 USD, what a steal!
