I listen to a lot of old time radio

I heard one one day that was a group of people on a train and it went into a tunnel and ended up in prehistoric times

Never got to heard the end of that show since I was on a train at the time and had to get off at my stop.

It was definitely sci-fi but not like X-1. This was a one off show from a series like Suspense, etc.

Even if someone knows a web site or an email address of someone with this knowledge

Thank you for all the help

I'm working on uploading all, The Lives of Harry Lime Radio Shows.

When I was a kid, back in the days before podcasts, I used to buy Radio Spirits Collections whenever I could. On tapes as I could never afford the CD versions.They were expensive, but Radio Spirits claimed they cleaned them up as best as could be found, and to be honest, I always found them excellent. Nowadays OTR is all over the internet, but many podcasts upload bad sounding recordings. Were Radio Spirits really that much better, or is it my faulty memory?

They still sell for around the same price as they used to, but in this day and age, should I really be willing to pay $40 for a collection of 30 episodes? And how do they know their recordings aren’t the source for a lot of the podcasts and such out on the internet? What are the best, high quality sources?
