==Gradient Profile==
The gradient profile of the SVR between Kidderminster and Bridgnorth is shown below. The diagram, which is reproduced from the SVR Visitor Guide Eighth Edition (2001), is based on official GWR documents.
[[File: SVR_Gradient_Profile.jpg|500px]]
The profile shows the average gradient in each section (the vertical scale is exaggerated), thus on leaving Kidderminster the line initially goes downhill with a gradient of 1 in 112. ‘L’ indicates level. According to the GWR gradient profiles, the steepest gradient on both the orignal Severn Valley Railway and the Loop line did not exceed an average of 1 in 100 in any section.
==Mileages==
The GWR generally location of stations, bridges and other structures on the railway network are measured distances to particular locations from a datum point (normally a major terminus). For the majority of the railways associated with the SVR the datum point was London Paddington via the most direct GWR route (the exact zero point being the Paddington Suburban Tunnel boundary with the Metropolitan Railway). The mileages individual routes used to reach those locations on are identified by [[Engineer's Line References]] (ELRs). Mileage Posts commonly appear at the original OWlineside, usually at &W route from Hartlebury via Kidderminster Junction frac14; mile intervals, to Kidderminster Station, and on confirm the relevant distances. The maps of the original Severn Valley Railway SVR shown below have been annotated with mileages taken from Hartlebury via Bewdley South Junction to Bridgnorth and Shrewsbury, were both measured from Paddington via Didcot and Worcesterthe relevant ELRs. Distances from London to principal stations All figures are shown in miles and chains were as follows (one chain is equal to 22 yards or 1/80th of a mile):===Oxford Worcester and Wolverhampton Line (OWW)===The ELR for the OWW began at Wolvercote Junction near Oxford (66 miles 32 chains from Paddington via Didcot). It ended at Priestfield Junction (140 miles 23 chains) near [[Wolverhampton]]. The section most relevant to the SVR is shown below.

|Bewdley } The SVR's [[Kidderminster |Kidderminster Town]] station is measured as 135 miles 40 chains (exactly 135&frac1/2; miles) from London. A milepost showing this distance is included in the gallery below. ===Severn Valley Branch (SVB)===The ELR for the SVB began in the south at Hartlebury Junction and ended at the junction with the Shrewsbury and Hereford Line (SHL) near Sutton Bridge Junction. Shrewsbury lay 62 chains north of this junction; however Shrewsbury was used as the datum point for the SHL. Thus the junction for the Wellington line, which came between the two is measured as 11 chains from Shrewsbury rather than a distance from Paddington. Similarly Woofferton is measured as 32 miles 11 chains from Shrewsbury. {| 137m 28chclass="wikitable"

Distances to places on the Loop were therefore measured on the basis that you would proceed towards Kidderminster and after passing [[Kidderminster Junction signal box#Kidderminster Junction | Kidderminster Junction]] at 135 miles 9 chains, reach a reversal point 12 chains further on. Returning over the 12 chains to the Junction on the loop line (now 135 miles 33 chains), mileages are measured until Bewdley South Junction is reached at 138 miles 21 chains. However Bewdley South Junction only 137 miles 12 chains via the direct route from Hartlebury; this lower figure becomes the base mileage for measuring distances onwards towards Bridgnorth and Tenbury. This accounts for the change in mileage at Bewdley South Junction in the profile above.{| class="wikitable"|-|135.21 [[File:BSicon_HST.svg|25px]] Mileage reversal point for BYK<br/>135.33 [[File:BSicon_ABZlf.svg|25px]] [[Kidderminster Junction signal box#Kidderminster Junction | Kidderminster Jct]] for OWW<br/>136.32 [[File:BSicon_HST.svg|25px]] [[Foley Park Halt]]<br/>137.43 [[File:BSicon_eHST.svg|25px]] [[Rifle Range Halt]]<br/>138.21 [[File:BSicon_ABZrf.svg|25px]] [[Bewdley South signal box|Bewdley Jct South]] with SVB (137.12)<br/>

Mileage posts showing the distance from London Paddington, as measured above, can be seen at the lineside. In the second example shown, the distance just south of Arley Station is 140¾ miles (the vertical bars below the number show the number of quarter miles). One mileage post is situated at the foot of Highley Signal Box, showing that it is exactly 143¼ miles from Paddington.

===Mileage oddities===
In addition to the 'discontinuity' in the mileage at Bewdley South Junction referred to above, the present day SVR being situated on three different ELRs gives rise to some other apparent oddities. Leaving Kidderminster, the mileage initially decreases as you pass the first milepost by the carriage shed but then increases again as you continue (due to setting off towards London but then curving away from it). Reaching Kidderminster Junction, this is two different distances from London, depending on whether you are on the OWW line or the Severn Valley Branch (due to the latter being approached by the reversal point). Finally, on Safari Park Curve you pass milepost 137¾, and a short time later you enter Bewdley Station passing another milepost 137¾ (the former being reached via the Loop and the latter direct via Hartlebury.
