Can we restrict connectivity to Railway site to specific list of IP addresses (e.g., Cloudflare IPs)

We do not offer built-in inbound IP allowlisting at the platform level. For application-layer protection like restricting traffic to specific IPs (e.g., Cloudflare), we recommend placing Cloudflare in front of your service as a WAF/proxy, as noted in our DDoS protection docs. You can then validate the X-Real-IP or X-Forwarded-For headers in your application, or use Cloudflare's firewall rules to restrict origin access.

We need to restrict access at the origin of Railway site to only Cloudflare IPs (i.e., inbound IP validation) . It's impossible to do this at Cloudflare

You can implement security rules under your domain in your Cloudflare configurations.
You'd set it up such that all traffic into your (sub)domain is blocked if the hostname isn't the desired IP address.
