What are the pros and cons of using flexible track in my layout?

One of the biggest advantages of using flexible track in a model railway layout is its ability to form curved and irregularly shaped track sections that would be difficult or impossible to create by other means. It is also relatively easy to install and adjust. Flexible track can also be cut to size, allowing for custom fitting in tight spaces.

The cons of using flexible track include its tendency to sag over time. This can lead to derailments, especially over longer track sections. It is also less durable than rigid track and may require more frequent replacement. As flexible track is generally used by modellers to create specific curves it will inevitably create compatibility issues for a modeller intending to use foam ballast, as the latter may not be able to match the shape of the track. Additionally, some hobbyists consider the appearance of flexible track to be less realistic than that of rigid track segments.

Flexible track certainly has its pros and cons but it is a useful alternative for a modeller to have in their toolkit when designing a layout. Like so many aspects of layout design, its use is a matter of personal choice by the modeller. Admittedly, it won't be the answer in all cases but there will inevitably be occasions where its use would be highly advantageous.
