We have not tested it ourselves: strengths and weaknesses below come from the tests cited.
Railfans who photograph from a platform end, a station footbridge or a roadside pull-off spend much of the day walking between positions, and this holster offers three ways to carry the camera: an integrated belt loop, a padded handle and a removable shoulder strap, all listed by Case Logic. The manufacturer also states that the base is padded to protect the camera and lens, which matters when a bag is set down on gravel, concrete or a bench between trains. For someone who wants to keep the camera ready while waiting for a scheduled freight or a heritage steam working, the quick-access lid is the feature that speaks most directly to the hobby.
The manufacturer lists the interior at 5.7 x 4.6 x 6.25 in and the exterior at 8.4 x 5.5 x 8 in, with a stated weight of 0.75 lb. That is a small bag, and it is built around one camera rather than a kit. Case Logic assigns the pockets specific jobs: the internal zippered pocket stores memory cards, a lens cloth and small accessories, while the side zippered pockets store an extra battery, cables, a lens cap or small accessories. For a session trackside, that layout keeps a spare battery and cards in the same bag as the camera, and the lens cloth has a place to live. The listed shoulder strap is removable, so the holster can be clipped to a belt for a long walk along a rail trail or carried by the handle when the strap would get in the way. Nothing on the manufacturer page describes weatherproofing, so rain protection would have to come from a separate cover.

A photographer who owns an SLR with a standard zoom lens and wants a simple holster for short outings to a station or a lineside spot. Because the manufacturer describes the fit as one SLR with a standard zoom attached, anyone who carries extra lenses, a longer telephoto or a larger camera body should compare the internal dimensions with their own equipment before choosing it, and a larger bag will suit a full day with a full kit better.
