You can buy corridor connections and have authentic bellows profiles, but it can become expensive if you have more than a few coaches. This is a very inexpensive generic concertina connection that requires no modifications to the structure or
paintwork of your model but, in my view, looks just fine from any reasonable viewing distance and fills that glaring gap between coaches that we see so often.
In the Januaryy/February 2025 edition of the N Gauge Society Journal there is a six page article showing in great detail how to make these corridore connections. Articles such as this alone make N Gauge Society membership at £18 per year a real bargain. The publication has now gone full colour and you get 6 per annum.
